How to Conduct a Phone Screen Interview at a Small Business

Phone screens are the most underused step in small business hiring. Most founders skip them entirely: they read resumes, pick the ones that look good, and jump straight to 45-minute interviews. The result is 8-10 interviews per role, half of which are with candidates who have deal-breaking salary expectations, cannot start for two months, or are not authorized to work in the US. A 15-minute phone call would have caught all of that.

A phone screen is not a mini interview. It is a filter. You are checking 4-5 deal-breakers: relevant experience, salary alignment, availability, work authorization, and basic communication skills. Anyone who clears these filters earns a full interview. Anyone who does not gets a polite rejection email and saves you both an hour.

This guide covers how to conduct phone screens at a small business: a ready-to-use 8-question script, a simple scorecard, the questions you legally cannot ask, and the step after the offer that most guides skip entirely. I built FirstHR to handle that last part, because the hiring process does not end at the offer letter.

What Is a Phone Screen Interview?

A phone screen interview is a short, structured call (15-20 minutes) between a hiring manager and a job candidate. Its purpose is narrow: determine whether this candidate should get a full interview. The phone screen checks deal-breakers that resumes cannot reveal: salary expectations, start date availability, work authorization, genuine interest in the role, and basic communication skills.

Phone screens save time by front-loading the questions that most commonly disqualify candidates. Without screening, these disqualifications surface 30 minutes into a full interview, after you have already invested preparation time, blocked your calendar, and potentially arranged for other team members to participate.

Phone Screen vs Phone Interview: Know the Difference

These terms are used interchangeably, but they describe different calls with different purposes. Confusing them leads to phone screens that run 45 minutes (too long) or interviews that only check logistics (too shallow).

At a small business, the same person typically conducts both calls. The distinction still matters because it changes your approach. In a phone screen, you are in filtering mode: check the boxes, move on. In a phone interview, you are in evaluation mode: dig deep, compare carefully.

Before the Call: 10-Minute Prep

Phone screens require less preparation than full interviews, but they still require preparation. Ten minutes before each call ensures you ask relevant questions and catch details that would otherwise slip by.

The 8-Question Phone Screen Script

These 8 questions cover the essential information you need from a phone screen. Ask them in this order to every candidate. The first two build rapport and check motivation. Questions 3-6 verify deal-breakers. Questions 7-8 assess communication and interest.

Total time: 12-15 minutes of candidate talk time plus your 2-minute opening overview. If a candidate's answer to Question 3 reveals a salary expectation 40% above your budget, you can politely end the call early. There is no reason to ask 5 more questions when the fundamental economic mismatch makes the hire impossible.

For phone screens, 8 questions are enough. More than 10 turns the screen into an interview.

Asking About Pay Without Breaking a State Law

Question 3 is the one that gets small employers into trouble, because two different waves of state law now govern it. The first wave bans asking what a candidate currently or previously earned. The second requires you to disclose your own range. They point in opposite directions, and both can apply to the same fifteen-minute call.

Start with the distinction that matters: salary history and salary expectations are not the same question. "What do you make now?" and "What did you earn at your last job?" are prohibited for private employers in well over a dozen states, including California, Colorado, Connecticut, Delaware, Hawaii, Illinois, Maine, Maryland, Massachusetts, Nevada, New Jersey, New York, Oregon, Rhode Island, Vermont and Washington, plus the District of Columbia and a number of cities. "What are your salary expectations for this role?" is generally still lawful, which is why the script uses that wording. If a candidate volunteers their current pay without being asked, some of those states allow you to consider it, but never as the justification for paying them less than you would pay someone else for the same work.

The disclosure side varies by both state and company size, which is where small employers get caught. Roughly a dozen states now require a pay range in job postings or on request, and the headcount trigger is different in each one.

Practically, this simplifies the call. Lead with your number instead of fishing for theirs: "The range for this role is $52,000 to $58,000 depending on experience. Does that work for what you are looking for?" That single sentence satisfies the disclosure duty in most jurisdictions, avoids the history question entirely, and gets you a cleaner answer than asking a candidate to guess first. If they say the range does not work, you have saved both of you an interview in about ten seconds. If they name a number 30 percent above the top of the range, ask once whether there is flexibility, and if not, close the call politely.

Scoring Candidates: A Simple System That Works

After 5-6 phone screens, candidates blur together. A scorecard prevents this by converting subjective impressions into comparable data.

Score each of the 8 questions during the call (not after). Calculate the total. Candidates scoring 28+ out of 40 move to full interviews. Candidates scoring below 20 are rejected. The 20-28 range requires judgment: review your notes, compare to other candidates, and decide based on the overall pattern.

The scorecard does not replace judgment. It structures it. When you have 6 candidates and need to pick 3 for interviews, a scorecard gives you an objective starting point instead of "I liked how she sounded on the phone."

Red Flags and Green Flags During a Phone Screen

Questions You Cannot Ask During a Phone Screen

The same EEOC rules that apply to full interviews apply to phone screens. Illegal questions asked casually on a phone call carry the same legal risk as illegal questions asked in a conference room.

The pattern: focus on job requirements, not personal identity. You can ask about ability to perform the role. You cannot ask about the person behind the candidate.

"We're Too Small for the EEOC" Is Usually Wrong

Federal coverage thresholds are real: Title VII and the ADA apply at 15 or more employees, and the ADEA at 20 or more. Below those counts, a small employer is often outside federal jurisdiction. That is where the reasoning usually stops, and it should not. Most states have their own fair employment statute with a far lower threshold, and several cover employers with a single employee — New York, Colorado and Michigan among them. California's FEHA reaches employers with five or more for discrimination and every employer regardless of size for harassment. The practical effect is that a nine-person business asking a candidate about her childcare arrangements is exposed in most of the country, just to a state agency rather than the EEOC. Screen as though you are covered, because you probably are.

The Work Authorization Question, Asked Correctly

Question 5 has an exact permitted form and several prohibited neighbors. Ask: "Are you legally authorized to work in the United States for any employer?" If sponsorship matters to you, add: "Will you now or in the future require sponsorship for an employment visa?" Ask both of every candidate for the role, not selectively based on a name or an accent. Do not ask whether the candidate is a US citizen, what country they are from, what visa they hold, or when they arrived. Do not ask for or accept documents during the screen — verification happens on Form I-9 after hire, and the employee chooses which acceptable documents to present. Demanding a specific document, or more documents than the form requires, is itself a violation. The anti-discrimination provision of the Immigration Reform and Control Act covers citizenship status claims against employers with four or more employees and is enforced by the Justice Department's Immigrant and Employee Rights Section, which also handles national origin claims for employers too small for the EEOC to reach.

Ability to Do the Job, Not Health

Before an offer, you may not ask about disability, diagnoses, medications, prior workers' compensation claims, or how many sick days a candidate used last year. You may describe the essential functions of the role and ask whether the candidate can perform them with or without reasonable accommodation. So "this role requires lifting up to 50 pounds repeatedly through an eight-hour shift — can you do that with or without accommodation?" is fine; "do you have any back problems?" is not. Medical inquiries and exams become permissible only after a conditional offer, and only when required of everyone entering that job category. If a candidate raises an accommodation need on their own during the screen, you can discuss it, but do not let it become the reason the call ends.

Can You Record the Call?

Recording phone screens is tempting once you are running six of them for one role, and AI note-taking tools have made it a one-click decision. It is not a one-click legal question. Federal wiretap law permits recording with the consent of one party, meaning you, but roughly a dozen states require the consent of everyone on the line. California, Florida, Illinois, Maryland, Massachusetts, Pennsylvania and Washington are among them. Because you are on the phone with someone who is frequently in another state, the reliable rule is to follow the strictest jurisdiction involved rather than your own.

Consent is easy to obtain and takes one sentence at the top of the call: "I record screening calls so I can take accurate notes — is that alright with you?" Wait for an audible yes, and note in the scorecard that consent was given and when. If the candidate declines, take written notes instead and do not treat the refusal as a mark against them.

Two further wrinkles apply if the tool is doing more than transcribing. Illinois's Biometric Information Privacy Act treats a voiceprint as a biometric identifier, so software that builds a voice profile or scores vocal characteristics triggers written-consent and retention-policy obligations, with a private right of action attached. And Illinois's AI Video Interview Act applies when you use AI to analyze a recorded video interview: it requires advance notice, an explanation of how the system works, consent before the interview, and deletion within 30 days of a candidate's request. If your screening stack analyzes candidates rather than just capturing what they said, treat it as a regulated tool and check the states your candidates sit in.

Edge Cases the Script Does Not Cover

The eight-question script handles the standard candidate. These are the situations where it does not fit, and what to do instead.

One question belongs in every screen for a remote or hybrid role and rarely appears in scripts: where will you actually be working from? The answer has cost consequences that arrive long before the first paycheck. Hiring an employee in a state where you have no presence generally means registering with that state for income tax withholding and unemployment insurance, and it can pull you into that state's paid sick leave, final pay, notice and pay transparency requirements, along with any local ordinance where they live. None of that is a reason to reject someone. It is a reason to know at minute twelve rather than the week before their start date, because the registrations take time and the payroll setup is not instant. If a candidate's location would put you in a new state, flag it to whoever runs your payroll before you extend the offer.

After the Call: Offer, Rejection, and the Onboarding Handoff

Phone screens produce three outcomes: advance, reject, or hold. Handle each within 48 hours.

For Candidates Advancing to Interview

Send a scheduling email within 24 hours. Include the interview format (in-person, video, or phone), expected duration, who they will meet, and anything they should prepare. Speed matters: top candidates are interviewing elsewhere, and delays cost you the best people.

For Candidates Not Advancing

Send a brief, respectful rejection email within 48 hours. Template: "Thank you for taking the time to speak with me about the [role] position. After careful consideration, we have decided to move forward with other candidates whose experience more closely matches the current requirements. I wish you the best in your search." Do not ghost candidates. It damages your employer brand in ways you cannot see.

After the Hire: The Step Most Guides Skip

The phone screen is step 1 of a process that ends at Day 90, not at the signed offer. After the interview stage produces a hire, the onboarding handoff begins: welcome email, compliance documents via e-signature (I-9, W-4), Day 1 schedule, training assignments, and a 30-60-90 day plan. I built FirstHR to handle this transition because it is where the hiring investment is either protected or wasted.

Common Phone Screen Mistakes

Six mistakes consistently undermine phone screening at small businesses. Most come from treating the phone screen as either too casual (no structure) or too intense (turning it into a full interview).

The common thread: phone screens fail when they lack structure (no questions, no scorecard, no timeline) or when they overreach (asking interview-depth questions in a 15-minute call). The sweet spot is a repeatable, consistent 15-minute process that produces the same quality shortlist every time.
