Fill forty seats without losing a month.

High-volume hiring fails in predictable places. The ad goes up before anyone agrees what good looks like, applications pile up faster than anyone can call them, and by the time a recruiter reaches applicant 300 the best ones have taken another offer. The fix is less about working harder and more about deciding things in the right order. This plan assumes one role, many seats, and about four weeks.

Start from the seats and work backwards

Before you write the ad, work out how many people you need at each stage. The numbers below are a worked example. The rates are assumptions, not benchmarks, so replace them with your own as soon as you have a week of real data.

Say you need 40 people to start on the same day.

So a 40-seat hire in this example needs roughly 650 people to look at your first round. If your job ad reaches 300, you already know you’re short, in week one instead of week four.

The same math tells you the workload. If 313 people finish a first round over two weeks, that’s about 30 a day to review. At five minutes each, that’s two and a half hours a day. As 20-minute phone screens, the 390 people who started would take about 130 hours of calls.

Week 0: agree the bar before the ad goes up

Spend one meeting with the hiring manager and settle four things.

• The three to five skills that predict success in the first 90 days. Not a wish list. For a support role that might be composure, clear explanation and ownership.
• The expected level for each. A beginner-level bar for a first job is different from an intermediate bar for experienced hires.
• The hard requirements. Shift availability, location, right to work, start date. Ask about these as plain questions, and read the answers yourself.
• Who can say yes. One named person makes final decisions. Committees slow volume hiring more than anything else.

Then write the first-round questions against those skills. Five or six situational questions (“A customer calls and says…”) tell you more than ten questions about the résumé. Keep the round short, around 15 minutes, because every extra minute costs you finishers.

Week 1: open the pipe

Post the ad with the first-round link in it, so applying and screening are the same step. Put the practical details in the ad: pay range, shifts, location, start date, and what the first round involves. Candidates who can’t work nights should find out before they spend fifteen minutes on an interview.

By the end of day three you have real numbers. Compare them to your assumptions:

• Few opens: the ad isn’t reaching enough people. Post it in more places or ask current staff for referrals.
• Many opens, few starts: the ad or the intro screen is putting people off. Check the length and the wording.
• Many starts, few finishes: the round is too long or a question is confusing.

Adjust once, early. Changing the questions every day makes candidates hard to compare.

Weeks 2 and 3: review every day, decide fast

Volume hiring rewards rhythm. Block the same hour every day for review and treat it like a meeting you can’t move.

1. Review everyone who finished since yesterday, strongest first.
2. For each person, check the evidence behind the rating, not just the number.
3. Move each person to one of three places: next round, on hold, or not this time.
4. Send the next-round invitations the same day.

Candidates who applied to you applied elsewhere too. A same-day reply is often the difference between an accepted offer and a polite no. Run final interviews in fixed blocks, for example two afternoons a week, so hiring managers can plan around them.

Week 4: offers, joining and the backfill

Make offers in batches, with a clear deadline to reply. Keep a ranked list of strong candidates you didn’t offer yet. Your acceptance and joining rates will almost never match your assumptions exactly, and those candidates are how you fill the gap without starting over.

Tell everyone who finished your first round where they stand. A short, kind message closes the loop. Silence after an interview is what candidates remember about a company.

Who does what

Most volume hires slow down when the recruiter and hiring manager each assume the other is doing something. Write it down.

The hiring manager doesn’t need to watch first-round interviews. They should read a few each week, so the bar doesn’t drift away from what they meant.

Where AI screening fits

The first round is the stage that doesn’t scale by hand. An AI interview lets every applicant take the same round the moment they apply, at 11pm or on a Sunday, and gives your daily review something consistent to read.

In LessRounds, you set the skills, level and weight for each, share one link in the ad, and review candidates scored per skill with a quote from the interview behind each score. The funnel on each link, from opened to shortlisted, fills in the bottom rows of the table above with real numbers. The software sorts. A person on your team still decides who moves forward.
