What a first round is for.

Most first-round interviews try to do too much. They ask about career goals, culture, strengths and weaknesses, then run out of time before checking whether the candidate can do the core of the job. A first round has a narrow purpose. It should answer one question: is this person worth an hour of a hiring manager’s time? Everything in it should help answer that, fairly and quickly.

The three jobs of round one

A good first round does three things and stops:

1. Confirm the basics. Can this person take the job as it actually is: the hours, the location, the start date, the pay range?
2. Check the must-have skills. Can they do the parts of the job they’ll need in their first month?
3. Give every candidate a fair shot. Same questions, same standard, a clear chance to show what they know.

If a question doesn’t serve one of those, it probably belongs in a later round or nowhere.

It helps to think about what a first round costs each side. For you, every extra minute is multiplied by every candidate. For the candidate, every extra minute is time they could spend on another application. A focused 15-minute round respects both. A 45-minute round that wanders through career history mostly tests patience, and the candidates with the most options are the first to leave.

A narrow first round also makes later rounds better. When round one has already confirmed the basics and the must-haves, the hiring manager can spend their hour on depth: how the candidate approaches harder problems, how they’d work with the team, and whether they want the job for the right reasons.

Confirm the basics

The basics are facts, not opinions, so ask them as facts. Short questions with clear answers work best:

• “This role is 7am to 4pm, Monday to Saturday. Can you work those hours?” (Yes / No)
• “Which of these locations could you work from?” (Multiple choice)
• “When could you start?” (Short text)
• “The pay for this role is $18 to $21 an hour. Does that work for you?” (Yes / No)
• For roles that require one, “Do you hold a valid driver’s license?” (Yes / No)

State the pay range up front. It saves both sides time, and candidates notice when you do.

Be careful about rejecting automatically on these answers. People misread questions, and “Can you start in two weeks?” answered “No” might mean three weeks. Read them before deciding. Leave out anything about personal life, such as age, family plans, health or religion. It isn’t relevant to the job, and asking can create legal risk.

Check the must-have skills

A must-have skill is one the person needs in their first month. Not their first year, and not something you’d like them to grow into. Most roles have two to four.

Test each one with a question about a situation they’ll actually face, rather than asking them to describe themselves. “Tell me about a time a customer was angry about something that wasn’t your fault” tells you more than “Are you good with customers?”

Four to six questions is usually enough. Fifteen to twenty minutes gives candidates room to answer properly without turning round one into round two.

Give every candidate a fair shot

Fairness in a first round is mostly about consistency and clarity:

• Ask everyone the same core questions. If different candidates get different questions, you can’t compare them.
• Score against the same standard, written down before you start, with the level you expect for this role.
• Say what you’re looking for. Candidates answer better when they know the interview is about how they handle situations, not trick questions.
• Let people take it at a time that works. A first round only during office hours filters out people with jobs, classes and caring duties.
• Don’t let accent, grammar or language choice count unless the job genuinely requires a specific language. If it does, make it an explicit skill.
• Tell them what happens next, and when.

Our guide on shortlisting fairly goes further on how to review results consistently.

What to leave for later rounds

Some things matter a lot and still don’t belong in round one:

• Deep technical assessment. Live coding, case studies and work samples take real time from both sides. Save them for people you already believe in.
• Team fit. Meeting the team is useful once you’re choosing between a few candidates, not forty.
• Pay negotiation. Confirm the range fits in round one. Negotiate at the offer.
• References. Check them near the end, for your final candidates.
• Selling the role in depth. Do it with people you want, in a live conversation.
• Practical checks. Driving, lifting, equipment and cooking tests need a person present.

A round-one checklist

Before you send out a first round, check that:

• Every question maps to a basic or a must-have skill.
• The must-have skills are written down with the level you expect.
• The pay range and hours are stated.
• Nothing asks about personal life or protected characteristics.
• The whole thing takes 20 minutes or less.
• Candidates can take it on a phone, at any hour.
• The invite says what happens next and when.
• Someone is ready to review results within a day or two.

An async first round meets most of that list by design. In LessRounds, screening answers are shown to you but never scored or used to reject anyone, spoken answers are scored per skill against the level you set, and each candidate’s interview is frozen when they start, so everyone gets the version they began with.
