Interior Designer Interview Questions and Scorecard
45+ interviewer questions across portfolio, documentation, client management, budget and sourcing, and behavior, each with what a strong answer sounds like, plus a portfolio walk-through and a 1-to-5 scorecard. Built for studios hiring without an HR department. Download as DOCX.
Interviewing an interior designer is unlike almost any other hire a small business makes, because the candidate arrives with a portfolio that has already done half the persuading. The images are beautiful, they were usually produced by a team, and they tell you what a studio shipped rather than what this person can do alone in your office next month. That gap is where design hires go wrong.
The fix is not to distrust the portfolio. It is to interrogate it, and then to test the three things a portfolio never shows: whether the candidate can issue drawings a contractor can build from, whether they can hold a client and a budget at the same time, and how they behave when a project goes sideways. Those are questions, and they have recognizable strong answers.
At FirstHR, we build for the studios and small firms that hire without an HR department, where the principal runs the whole interview between a client presentation and a site visit. This page gives you 45+ interviewer questions grouped into six sets, with what a strong answer sounds like for each, plus a portfolio walk-through and a downloadable 1-to-5 scorecard.
TL;DR
Interview an interior designer on five things: portfolio and design process, technical documentation and software, client management, budget and sourcing, and behavioral evidence. Run the portfolio as a walk-through, asking on every project which parts were their own work. Ask the same core questions of every candidate and score each competency 1 to 5, so a portfolio that photographs well does not decide the hire on its own.
What to Assess in an Interior Designer
Assess an interior designer on five competencies: design process, technical documentation, client management, budget and sourcing, and behavioral evidence. Taste matters, but taste is the one thing the portfolio already tells you, so the interview should spend its time on the four things it does not.
The order matters too. Start with the portfolio, because it is the candidate's home ground and it relaxes them, then move outward into the areas nobody rehearses. A designer who has genuinely run projects answers the budget and sourcing questions as easily as the concept questions. One who has only ever supported another designer starts hedging around the third follow-up.
The most reliable way to run this is a structured interview, where every candidate answers the same core questions scored on the same rubric. Design hiring is unusually vulnerable to the alternative, because a candidate whose aesthetic happens to match yours can feel like an obvious fit on no evidence at all.
The Six Question Sets
The questions below are grouped into five competencies plus a scorecard. Each set targets a different part of the role, and a strong candidate should hold up across all of them, not only on the portfolio questions they have told a hundred times.
Portfolio and Design Process
Is the work theirs?
How they get from a brief to a built room, and which parts of the portfolio they personally did. The single most revealing part of the interview.
Technical and Documentation
Can a contractor build it?
Software, drawing sets, dimensioning, ceiling and lighting plans, millwork details, finish and FF&E schedules, clearances and accessibility.
Client Management
Can they hold a client?
Running a brief meeting, presenting options, saying no well, handling changed minds, and confirming decisions in writing before they cost money.
Budget and Sourcing
Do they own the money?
Budget structure, contingency, vendor relationships, lead times, substitutions, contractor coordination, punch list, and closeout.
Behavioral and Situational
How do they handle wrong?
STAR-style questions on overruns, drawing errors, difficult installs, and disagreements with the architect or the general contractor.
Scorecard and Red Flags
Score, do not guess
A 1-to-5 rubric plus a red-flag checklist, so a portfolio that photographs well does not decide the hire on its own.
Weight the Sets to the Work You Sell
Residential studios should push hardest on client management and on budget and sourcing, because the designer will be running procurement and installation directly with the homeowner. Commercial firms should push hardest on the technical set, because the work lives or dies on drawing sets, clearances, and coordination with the architect and the general contractor. If you sell both, test both. Ask at least two questions from every set regardless, and use the scorecard so a brilliant answer in one area does not paper over a hollow one in another.

Set 1: Portfolio and Design Process
How the candidate gets from a brief to a built room, and which parts of the portfolio are genuinely their own. Start here: it is the most revealing set on the page.
Portfolio and Design Process Questions
INTERIOR DESIGNER INTERVIEW: PORTFOLIO AND DESIGN PROCESS
Candidate: __
Interviewer: __
Date: __
QUESTIONS TO ASK
•Walk me through the project you are proudest of, from the first client
meeting through installation day.
•On that project, which parts did you personally do, and which were done by
others on the team?
•How do you get from a brief and a set of site measurements to a concept?
•Talk me through your sequence: programming, space planning, concept, design
•Show me a project that did not turn out the way you drew it. What changed,
and who made the call?
•Which project here had the tightest budget, and how did that change your
design decisions?
•How do you present a concept to a client who cannot read a floor plan?
•What kind of work is in your portfolio that you would rather not do again?
WHAT A STRONG ANSWER LOOKS LIKE
A strong candidate separates their own contribution from the team’s without
being asked twice, and describes a repeatable sequence rather than a burst of
inspiration. Listen for constraints treated as design inputs: budget, existing
conditions, code, lead times. The best answers explain decisions in terms of
what the client needed, not what the designer liked. Weak answers present
finished photography with no process behind it, or blur whose work it was.
NOTES
[Capture the specific projects discussed, the candidate’s actual role, and any
gaps between the portfolio images and the story told.]
Set 2: Technical Skills and Documentation
Software, drawing sets, dimensioning, ceiling and lighting plans, millwork details, finish and FF&E schedules, and how they check clearances and accessibility before documents go out.
Technical Skills and Documentation Questions
INTERIOR DESIGNER INTERVIEW: TECHNICAL SKILLS AND DOCUMENTATION
Candidate: __
Interviewer: __
Date: __
QUESTIONS TO ASK
•Which drawing and modeling software do you use daily, and what do you
actually produce in each?
•Describe the last drawing set you issued. Which sheets were in it?
•How do you dimension and annotate a plan so a contractor can build from it
without calling you every morning?
•Walk me through how you lay out a reflected ceiling plan and a lighting plan.
•What is your experience detailing millwork and casework?
•How do you build and maintain a finish schedule and an FF&E specification?
•On a commercial project, how do you check clearances, egress, and
accessibility before the drawings go out?
•How do you handle renderings and client-facing visuals, and how do you keep
them honest about what will actually be built?
WHAT A STRONG ANSWER LOOKS LIKE
A strong candidate names the tools and says what comes out of each one, for
example modeling in one, construction documents in another, presentation
boards in a third. They can describe a real sheet set: demolition plan, floor
Running a brief meeting, presenting options, saying no well, handling a client who changes their mind after sign-off, and confirming decisions in writing before they cost money.
Client Management and Communication Questions
INTERIOR DESIGNER INTERVIEW: CLIENT MANAGEMENT AND COMMUNICATION
Candidate: __
Interviewer: __
Date: __
QUESTIONS TO ASK
•How do you run a first client meeting so you leave with a real brief rather
than a wish list?
•What do you do when a client asks for something you believe is a mistake?
•How do you present options without overwhelming someone?
•A client signs off on a scheme, then changes their mind three weeks later.
What happens next?
•How do you communicate a change order and its cost impact?
•Tell me about a client who did not like your design. How did it end?
•How do you set expectations about lead times and delays at the start, before
anything has gone wrong?
•How much of your past work involved winning the client, not just doing the
design?
WHAT A STRONG ANSWER LOOKS LIKE
Strong candidates ask before they propose, and they document decisions in
writing so a sign-off means something. They distinguish a client’s taste from
a client’s requirement, present options with tradeoffs and prices attached,
and have an actual process for scope changes rather than absorbing revision
after revision in silence. Listen for someone who delivers bad news early.
Weak answers describe clients as obstacles, take rejection personally, or show
no habit of confirming anything in writing.
NOTES
[Capture how the candidate handles disagreement, and whether they have ever
had to hold a scope line with a paying client.]
Set 4: Budget, Sourcing, and Project Management
Budget structure and contingency, vendor relationships and lead times, substitutions, contractor coordination, punch list, and closeout. The set that separates designing from delivering.
Budget, Sourcing, and Project Management Questions
INTERIOR DESIGNER INTERVIEW: BUDGET, SOURCING, AND PROJECT MANAGEMENT
Candidate: __
Interviewer: __
Date: __
QUESTIONS TO ASK
•At what stage do you build a budget, and how do you structure it?
•How do you bring a design back inside budget without gutting it?
•A specified piece is discontinued eight weeks before install. Walk me
through what you do.
•Take me through how you place, track, and receive a furniture order.
•Which vendors and trade reps do you know well, and what have you learned
about their lead times?
•How do you coordinate with a general contractor when field conditions do not
match the drawings?
•How do you run a punch list and close a project out?
•How many projects have you run at once, and how did you keep them straight?
WHAT A STRONG ANSWER LOOKS LIKE
A strong candidate has a numbers habit: allowances by category, a contingency,
and a view of where the money actually goes. They name real vendor
relationships instead of speaking about sourcing in the abstract, they plan
around lead times rather than discovering them, and they treat substitutions
as a routine part of the job with a documented client approval step. Listen
for site visits, a real punch list, and closeout. Weak answers have never
touched a budget, have no procurement experience, and blame contractors
generically.
NOTES
[Record the largest budget the candidate has personally managed and whether
they have owned procurement or only design.]
Set 5: Behavioral and Situational
Past behavior as the best predictor: overruns, drawing errors that reached the field, difficult installation days, and disagreements with the architect or the general contractor.
Behavioral and Situational Questions
INTERIOR DESIGNER INTERVIEW: BEHAVIORAL AND SITUATIONAL
Candidate: __
Interviewer: __
Date: __
QUESTIONS TO ASK
•Tell me about a project that went over budget. What did you do about it?
•Describe a time you had to tell a client no.
•Tell me about an error in a drawing or a specification that reached the
field. How was it caught, and what changed afterward?
•Describe a disagreement with an architect or a contractor and how it ended.
•Tell me about a project where the required style was nothing like your own
taste. How did you approach it?
•Describe the hardest installation day you have had.
•Tell me about feedback that changed the way you work.
•Describe a time you had to hand a project to someone else. How did you
package it?
WHAT A STRONG ANSWER LOOKS LIKE
Evaluate with the STAR pattern: a real Situation and Task, the specific Action
this candidate took, and a Result you can picture. In a portfolio profession,
the most useful signal is how someone handles being wrong, because drawings
have errors and installations go sideways. Strong answers own the mistake and
name what changed in their process afterward. Watch for candidates who cannot
produce a single example of a project going badly.
NOTES
[Capture the situation, the action, and the result for each example, plus any
pattern of blaming clients, contractors, or vendors.]

How to Run the Portfolio Walk-Through
Run the portfolio as an interview, not a viewing. The candidate narrates, you ask, and the questions are the same for everyone. Budget 30 to 40 minutes for it, which is longer than most interviewers expect, because this is where the evidence is.
The single most useful move is to let the candidate choose the first project and then choose the second one yourself. The rehearsed project shows you their best work; the unrehearsed one shows you their process. Ask the same four questions on both.
Pick the project, do not let them pick it
Let the candidate choose one, then you choose the second. The project a designer did not rehearse is where the real process shows.
Ask what was theirs
On every image: who did the space plan, who drew the details, who specified the finishes, who was on site. Vague answers here are the loudest signal in the whole interview.
Ask what it cost
Budget, where the money went, and what got value-engineered out. A designer who has never seen the number has not run a project.
Ask what went wrong
Every built project has a substitution, a delay, or a field condition that broke the drawing. The story of the fix tells you more than the finished photo.
Ask about every project
What a strong answer includes
Which parts were your own work?
Specific: space plan, details, specification, site visits
What was the budget?
A real number, where it went, what got cut
What changed from the drawings?
A substitution or field condition, and how it was approved
Who else was on the project?
Names the architect, contractor, and team without prompting
Can I see a drawing set?
Produces documents, not only styled photography
If the role involves construction documents, ask for a drawing set explicitly. Plenty of strong presenters have never issued one, and you will not discover that from photographs. A candidate who cannot show documents can still be right for a residential styling role, but you should know which hire you are making.
Residential and Commercial Need Different Questions
Residential and commercial interior design share a skill base and diverge sharply in practice, so the interview should diverge too. Residential designers usually own procurement and installation directly with the homeowner; commercial designers usually own documentation, code, and coordination with an architect and a general contractor.
What the role involves
Residential
Commercial
Space planning and finish specification
The client is the daily end user of the space
Permit sets and code review are routine
Accessibility compliance is a core requirement
The designer purchases, tracks, and receives furniture
State title registration may apply
The practical consequence is that a strong residential designer can look weak in a commercial interview and the reverse is equally true. Decide which you are hiring before the first call, say so in the posting, and weight the question sets accordingly. If a candidate is crossing over, ask directly what they have not done yet, and treat a straight answer as a positive signal.
What to Probe For (and Red Flags)
The questions get you started; the follow-ups decide the hire. Push for the specific number, the actual drawing, the real conversation with the client, and watch for the patterns that separate a designer who has delivered projects from one who has only contributed to them.
Ownership of the work
Names their own contribution project by project
Credits collaborators without being prompted
Can produce drawings, not only photographs
Technical depth
Describes a real sheet set from memory
Coordinates ceilings, lighting, and millwork
Treats clearances and accessibility as design inputs
Commercial instinct
Knows what their projects cost
Confirms scope changes in writing
Delivers bad news early, not at install
Red flags
Taste and mood with no process behind it
Has never worked to a budget
No example of a project that went wrong
Three questions carry more weight than the rest. What was your part in this. What did it cost. What went wrong. A candidate who answers all three cleanly has run real projects, and a candidate who deflects on any of them is telling you something worth writing on the scorecard.
Walk me through your process from brief to installation.
Strong answer: Names a sequence and sticks to it: programming and measurement, space planning, concept, design development, specification, procurement, site coordination, punch list. A strong answer attaches real decisions to each stage and says where the client signs off.
Weak answer: A weak answer jumps straight from inspiration to finished photos, with nothing between the mood board and the install, and no sign-off points at all.
A specified sofa is discontinued eight weeks before install. What do you do?
Strong answer: Checks the lead time on alternates before promising anything, brings the client two options with prices and photographs, gets the substitution approved in writing, and updates the FF&E schedule and the budget. Tells the client the same day, not the week before install.
Weak answer: A weak answer substitutes quietly and hopes nobody notices, or escalates it to the owner without having done any of the legwork first.
How do you make sure a contractor can build from your drawings?
Strong answer: Talks about dimensioning to a consistent reference, coordinating the reflected ceiling plan with the mechanical and lighting layout, detailing the millwork properly, and being reachable on site. A strong answer mentions the RFIs they used to get and how they stopped getting them.
Weak answer: A weak answer has only ever produced presentation drawings, or assumes the contractor will figure the details out on their own.
Credentials, Licensure, and What to Require
Set the credential requirement before you interview, because getting it wrong is expensive in both directions. The NCIDQ examination, administered by the Council for Interior Design Qualification, combines education, supervised experience, and a multi-part exam, and it is held by a minority of practicing designers.
State rules then vary sharply. According to the Bureau of Labor Statistics, some states allow only licensed designers to do interior design work, some allow anyone to do the work but restrict who may use the title interior designer, and some do neither. Check your own state before you write the requirement into the job description.
Not required
Most residential work in most states. Requiring a certification here filters out the majority of qualified designers for no legal or practical benefit.
Preferred
Mixed studios and larger residential work. Signals a bar without closing the door on a strong self-taught or degree-only candidate.
Required for this role
Commercial work in a state that regulates the title or the practice, or work that has to be stamped and permitted. Ask for the certificate number and verify it.
Ask either way
Education, supervised hours, and whether they are working toward certification. A candidate mid-qualification is often the best value a small studio can hire.
A Credential Line Set Wrong Costs You Either Candidates or Compliance
Requiring certification for a junior or residential role in a state that does not regulate the profession removes most qualified applicants from your pipeline for no legal or practical benefit. Leaving it out for permitted commercial work in a state that restricts practice creates real exposure instead. Commercial roles carry an accessibility layer as well, since the Americans with Disabilities Act governs the commercial interiors the work produces, which is why the technical question set asks how the candidate checks clearances and egress before documents go out. Verify your state rules with the relevant state board. This is general information, not legal advice.
Whatever you decide, ask every candidate about education, supervised hours, and whether they are working toward certification. A designer partway through qualification is often the strongest value a small studio can hire, and offering to cover exam fees costs little while reading as genuine career investment.

Interior designer pay varies widely by seniority, project type, metropolitan area, and whether the role includes procurement and business development. Use federal data as the baseline, then adjust for your market and the scope you actually need.
Median $67,190 a Year (BLS OEWS, May 2025)
According to the Bureau of Labor Statistics Occupational Employment and Wage Statistics survey (May 2025), interior designers earned a median of $67,190 per year, about $32.31 per hour. The lowest 10 percent earned $41,420 or less and the highest 10 percent earned $114,140 or more, with the 25th percentile at $51,840 and the 75th at $85,740 (U.S. Bureau of Labor Statistics).
That spread is wide because the occupation covers a junior designer in a two-person residential studio and a senior commercial designer running tenant-improvement packages. Publish a band in the posting rather than leaving it out, and be careful about salary history, which several states and cities prohibit employers from asking about.
If the role is project-based or seasonal, decide early whether you are hiring an employee or engaging a contractor, because that choice changes the paperwork, the tax treatment, and how much control you can exercise over the work. Get it right before the offer goes out, not after.
Fair, Legal, and Structured Interviewing
A good interview is fair, legal, and structured, and the three reinforce each other. Asking the same job-related questions of every candidate keeps you compliant, reduces bias, and produces better hires at the same time. This is the part that generic question lists skip entirely.
Ask about the work, not the person
Federal anti-discrimination law, enforced by the EEOC, prohibits basing hiring decisions on protected characteristics, and questions that probe them create risk even when they feel like friendly rapport. Avoid age, race, religion, national origin, sex, pregnancy or family plans, disability, and genetic information. A design interview has its own version of this trap, because portfolio conversations drift easily into someone’s home life, their travels, or where they grew up as a way of talking about taste. Keep the conversation on the projects, the drawings, the budgets, and the clients. Every question in the sets on this page is written to stay on the job. This is general information, not legal advice.
Use the same core questions for every candidate
Asking each candidate the same core set of questions is fairer and it produces better hires. A structured interview, where everyone faces the same questions scored against the same rubric, predicts on-the-job performance far better than a free-flowing conversation, and it makes a portfolio profession much harder to judge on charm. Design hiring is unusually vulnerable to this, because a candidate whose aesthetic happens to match yours can feel like a great fit on no evidence at all. Write the questions in advance, ask them in the same order, and score them. This is general information, not legal advice.
Score independently, then discuss
When more than one person sits in, have each interviewer complete the scorecard alone before the group talks. This stops the principal or the most senior designer from anchoring everyone else, which is how strong candidates get talked out of and weak ones get talked into. In a studio, the portfolio review makes this worse, because reactions to images are immediate and contagious. Compare written evidence first, discuss the gaps second. A simple 1-to-5 rubric per competency, filled in independently, turns an aesthetic debate into a structured decision you can defend later.
Match the questions to the work you actually sell
A designer for a two-person residential studio and one for a commercial firm doing tenant improvements are different hires, so weight the sets accordingly. Residential work leans on client management, procurement, and installation, so push hard on the budget and sourcing questions. Commercial work leans on documentation, code, clearances, and coordination with the architect and the general contractor, so push hard on the technical set. If you sell both, say so in the interview and test both, rather than hiring a specialist and hoping they stretch. Decide what the role must deliver in its first 90 days and interview for that.
Same Questions, Scored on a Rubric, Predict Better Hires
A structured interview, where every candidate answers the same questions scored against a consistent rubric, predicts on-the-job performance more reliably than an unstructured conversation, and SHRM advises using the same criteria for every candidate for exactly this reason. Asking the same job-related questions of everyone also keeps you within the EEOC rules against basing decisions on protected characteristics.
Design interviews have their own version of the small-talk trap, because a conversation about someone's taste drifts easily into their home, their family, or where they grew up. Keep it on the projects and avoid the questions you cannot ask. This is general information, not legal advice.
Interviewing a Designer Without an HR Department
At a large firm, a designer candidate goes through coordinated panels with a recruiter managing scorecards and a design director reviewing the portfolio. At a small studio, the principal runs the interview alone, and one bad hire on a three-person team is felt on every project. Here is how to make that single interview rigorous.
You are the principal, the hiring manager, and the only interviewer
Most interior design studios that hire a designer are small enough that the owner runs the whole interview alone, between a client presentation and a site visit. There is no recruiter to prepare a question bank and no panel to balance a first impression. The six sets here are built for exactly that: pick the categories that match your work, ask the same questions of every candidate, and fill in the scorecard while the answers are fresh. The goal is to make one principal’s interview as rigorous as a full hiring team’s, without any of the overhead.
A beautiful portfolio is the easiest thing in this profession to misread
Portfolio images are produced work: styled, photographed, and often the output of a team. They tell you what a studio shipped, not what this candidate can do alone in your office next month. That is why the portfolio walk-through on this page is a set of questions rather than a viewing, and why the scorecard separates design process from documentation, budget, and client management. A designer can be genuinely talented and still be unable to issue a drawing set a contractor can build from, and the interview is the only place you will find that out before the hire.
The interview is step one; the offer and onboarding are where it gets real
Once you pick a designer, the job shifts from evaluating to hiring well: a clear written offer, the new-hire paperwork, software and vendor-portal access, and a structured first 90 days so they are billable rather than shadowing. This is the part FirstHR covers for a small studio: send the offer for e-signature, run the paperwork and the onboarding workflow, assign the access and policy tasks, and keep the signed documents and interview records on the employee profile. To be clear on scope, FirstHR is an onboarding and HR platform, not design, rendering, or project-management software, so pair it with those. Applicant tracking is coming soon to FirstHR.
Two habits do most of the work at this size. Fill in the scorecard immediately after each interview while the answers are fresh, and actually call the references, asking specifically about budget discipline and how the designer behaved when a project went wrong. A reference check on a portfolio hire is worth more than on almost any other role, because it verifies the one thing the portfolio cannot. Applicant tracking is coming soon to FirstHR.
From Interview to Hire
The interview is step one. Once you choose a designer, the work shifts to hiring well: a clear offer letter, the paperwork, software licenses and vendor-portal access, and a structured first 90 days so the new hire is billable rather than shadowing. Ramp time is real money in a studio that bills by the hour.
Prepare the question set
Pick the sets that match residential or commercial work and use the same core questions for every candidate, so the comparison is fair.
Score on the rubric
Each interviewer completes the 1-to-5 scorecard independently with evidence from the portfolio walk-through, then the group compares.
Send the offer
Confirm scope, compensation, and start date in writing, with e-signature, so there is a clean record before day one.
Onboard for the first 90 days
Software licenses, vendor portals, drawing standards, and a first project with a named mentor, so the designer is billable quickly.
Give the new designer your drawing standards, your specification format, and a first project with a named mentor in the first week. Small studios often skip this because everyone is busy, and then spend three months correcting habits that could have been set on day two with an onboarding template.
FirstHR connects the offer, e-signatures, the new-hire paperwork, and the access and policy checklist in one place, and keeps the signed documents and interview records on the employee profile, so a studio can run hiring to onboarding from one system. If the same round is also filling drafting or graphics roles, the CAD designer templates cover those postings, and the scorecard here adapts with the technical areas rewritten for scope. Applicant tracking is coming soon to FirstHR.
Assess an interior designer on design process, technical documentation, client management, budget and sourcing, and behavioral evidence, not on the portfolio alone.
Run the portfolio as a walk-through: let the candidate pick one project, pick the second yourself, and ask which parts were their own work.
Three questions carry the most weight: what was your part, what did it cost, and what went wrong.
Weight the sets to your work, since residential leans on procurement and clients while commercial leans on documents, code, and coordination.
Set the credential requirement before you interview, because state rules on the interior designer title and practice vary widely.
Score each competency 1 to 5 independently and run the red-flag checklist before the group discusses, so no single impression anchors the decision.
Frequently Asked Questions
What questions should I ask when hiring an interior designer?
Ask across five areas: portfolio and design process, technical documentation and software, client management, budget and sourcing, and behavioral evidence. The highest-value questions are specific rather than general. Walk me through the project you are proudest of, from the first client meeting to installation day. Which parts of it did you personally do. Describe the last drawing set you issued and the sheets in it. A specified piece is discontinued eight weeks before install, what do you do. Tell me about a project that went over budget. Each of these forces a real story instead of a statement of taste, and each has a recognizable strong answer you can score. The six downloadable sets on this page group the questions by competency and pair every set with notes on what a strong answer sounds like.
How do I evaluate an interior designer’s portfolio in an interview?
Treat the portfolio as a set of questions rather than a viewing. Let the candidate pick the first project, then you pick the second, because the unrehearsed one shows the real process. On every project, ask who did the space plan, who drew the details, who specified the finishes, and who was on site, since portfolio images are usually team output. Ask what the budget was and where the money went. Ask what went wrong, because every built project has a substitution, a delay, or a field condition that broke a drawing, and the story of the fix is more informative than the finished photograph. If the role involves construction documents, ask to see a drawing set, not only styled photography. Vagueness about personal contribution is the single loudest warning sign in a design interview.
What is the difference between an interior designer and an interior decorator?
An interior designer works on the space itself: programming, space planning, non-structural changes, lighting and ceiling layouts, millwork details, finish and furniture specification, and coordination with architects and contractors, often producing construction documents. An interior decorator focuses on the surface layer of an existing space, meaning furnishings, color, textiles, and styling, without altering the layout or producing permit-level drawings. The distinction matters when you write the job posting and again when you interview, because a decorator interviewing for a designer role will present beautiful work and then struggle with the documentation and coordination questions. Decide which the role actually needs before the first interview, and weight the technical set accordingly. In states that regulate the interior design title, the distinction can also carry legal weight.
Should I require NCIDQ certification when hiring an interior designer?
It depends on your work and your state, and getting this wrong is expensive in both directions. The NCIDQ examination, administered by the Council for Interior Design Qualification, combines education, supervised experience, and a multi-part exam, and it is held by a minority of practicing designers. Requiring it for a junior or residential role in a state that does not regulate the profession filters out most qualified candidates for no practical benefit. Failing to require it for commercial work in a state that restricts the title or the practice creates real exposure. According to the Bureau of Labor Statistics, licensure rules vary by state: some restrict the work itself, some restrict only the title, and some do neither. Check your state first, then set the requirement as not required, preferred, or required for this specific role. This is general information, not legal advice.
How much do interior designers earn?
According to the Bureau of Labor Statistics Occupational Employment and Wage Statistics survey (May 2025), interior designers earned a median of $67,190 per year, about $32.31 per hour. The lowest 10 percent earned $41,420 or less and the highest 10 percent earned $114,140 or more, with the 25th percentile at $51,840 and the 75th at $85,740. That spread is wide because the occupation covers junior designers in small residential studios and senior commercial designers running large tenant-improvement projects. Pay also varies sharply by metropolitan area, by project type, and by whether the role includes procurement and business development. Benchmark to your local market and to the scope you actually need, publish a band in the posting, and do not ask candidates for their salary history in jurisdictions that prohibit it. This is general information, not legal advice.
What are the red flags in an interior designer interview?
Watch for six. First, the candidate cannot say which parts of a portfolio project were their own work. Second, they describe taste and mood with no process behind them, so there is nothing between the concept and the finished photograph. Third, they have never worked to a budget or seen a purchase order, which means they have designed but not delivered. Fourth, they treat code, clearances, and accessibility as somebody else’s department on work where those are their responsibility. Fifth, they cannot produce a single example of a project that went wrong, which in a profession full of substitutions and field conditions is not credible. Sixth, they speak about clients, contractors, or vendors with contempt. The downloadable scorecard includes this list as a checkbox so it gets used rather than remembered.
Should I give an interior designer candidate a design test?
A short, paid exercise is reasonable and often decisive, but keep it small and never use it as free work. A good version takes two or three hours: a simple space plan for a room with real dimensions and a stated budget, a short finish or furniture specification, and a paragraph explaining the choices. That tells you about space planning, budget discipline, specification habits, and written communication in one pass. Do not ask for a full concept package for one of your live client projects, which is unpaid labor and damages your reputation among designers who talk to each other. Pay for the time, give every finalist the same brief, and score the results on the same criteria as the interview so the exercise strengthens the structured process rather than replacing it.
How long should an interior designer interview take?
Plan 60 to 90 minutes, which is longer than a typical first-round interview because the portfolio walk-through needs real time. A practical split is 30 to 40 minutes on the portfolio, 20 minutes on technical documentation and budget questions, 15 minutes on client management and behavioral questions, and the rest for the candidate’s own questions, which reveal how they think about the studio. Resist cramming in every question on this page. Depth beats breadth, because the follow-ups on a few strong questions tell you more than a rushed checklist. Score immediately afterward while the answers are fresh, and if a second round is needed, use it for a paid exercise and a conversation with whoever the designer would coordinate with day to day.
