How to replace phone screening calls.

A phone screen is a short first interview by phone. It’s the most common first step in hiring, and one that few teams question. A recruiter calls, asks some questions, takes notes, and decides whether the candidate goes on. It feels cheap because each call is short. Add up the calls, the scheduling and the candidates you never had time to call, and it usually isn’t. This guide covers what a phone screen is actually for, what to keep, what it costs, and how to switch without losing anything that matters.

What a phone screen is for

Ask five recruiters what their phone screen checks and you’ll get a similar list:

1. Logistics. Location, availability, start date, pay expectations.
2. Must-have skills. Can this person do the core of the job, at the level the role needs?
3. Communication. Can they explain themselves clearly?
4. Interest. Do they understand the role and want it?
5. Selling. Answering their questions and making the role attractive.

The first four are about gathering information. Only the fifth truly needs a live conversation, and it matters most for candidates you already want.

What to keep

Before you replace anything, decide where each of these tasks will happen instead.

You still make a call. It just happens later, only with people you already know are worth it, and it’s shorter because you already have the basic facts.

One thing worth keeping from a good phone call is the recruiter’s sense of what to ask. Write their best questions down. If your best recruiter always asks “What would your last manager say you should work on?” because the answers are revealing, that question belongs in the new interview. The goal is to write down the questions your team already knows work, then ask them of every candidate, not only the ones who happened to get a call.

What it costs: a worked example

These numbers are assumptions for illustration, not industry figures. Swap in your own.

Assumptions: one role, 150 applicants. A résumé check leaves 60 worth a conversation, but the recruiter only has time to call 30. Each call takes 20 minutes, plus 10 minutes of scheduling, rescheduling and notes. Recruiter time costs $45 an hour, including salary and overheads. For the AI interview route, all 60 are invited and 40 complete. The recruiter spends 3 minutes skimming each write-up and 10 more on the top 15.

The tool cost uses LessRounds’s pricing: $5 for each finished interview of up to 30 minutes. It leaves out the 100 free credits a new account starts with, which would cover the first 20. Check the pricing of whatever tool you’re comparing.

The bigger difference isn’t in the table. The 15 hours of calls had to fit into calendars over a week or more. The 4.5 hours of review can happen in one sitting, the morning after candidates finish. For your own numbers, try the phone screen cost calculator.

What changes when candidates interview on their own time

• Everyone gets the same questions. The eighth candidate of the afternoon gets the same interview as the first.
• Candidates choose the time. People with jobs, classes or other time zones stop dropping out over scheduling.
• You review evidence, not notes. Instead of a recruiter’s summary of a call, you read the candidate’s actual words and a score per skill.
• Candidates who don’t show up stop costing you time. An interview nobody starts takes none of your time.

What you lose is the moment in a live call when a recruiter spots something interesting and asks more about it. An AI interview with follow-up questions gets some of that back. The rest can wait for the second interview.

You also lose an early chance to sell the job to the candidate. For roles where good candidates have several offers, that matters. The fix is to be quick. If strong candidates hear from a person within a day of finishing, you lose nothing on selling the job, and you save the week you’d have spent scheduling calls.

How to switch, step by step

1. Write down what your phone screen checks today. Use your actual notes, not the ideal version.
2. Split the list into facts and skills. Facts become screening questions. Skills become spoken questions.
3. Build a 15- to 20-minute interview. Four to six spoken questions is usually enough for a first interview. Our guide on writing pre-screening questions helps here.
4. Try both at once on one job. Send the AI interview to everyone, and still phone a handful of candidates. Compare who you’d move forward from each.
5. Rewrite the invite. Say it’s an AI interview, how long it takes, and when you’ll be in touch. The invite email template is a starting point.
6. Replace the first phone call with a call for your shortlist. Fifteen minutes, for candidates who passed, focused on their questions and on selling the role.

What to watch in the first month

• How many candidates finish, by where they applied. If one job board’s applicants rarely finish, the invite or the role description may need work there.
• Set-aside candidates. Read a sample. If people you’d have hired are landing below your pass mark, adjust it or the skills.
• Whether your team agrees with the results. When a hiring manager disagrees with a shortlist, find out which skill they’d have scored differently.
• Candidate feedback. Ask two or three candidates how it felt. It’s the fastest way to find a confusing question.
