Knockout Questions for Job Applications: What to Ask and What to Avoid

Knockout questions are application questions with a required answer, such as the right to work in the country or holding a licence the job legally needs. Use them only for true requirements, keep them few, word them neutrally, and have a person review anyone flagged, because a wrong or unfair automatic rejection loses good candidates and can create legal risk.

Use them for real must-haves

Good knockout questions are about legal or practical requirements: the right to work, a required licence or certificate, availability for the shifts, a willingness to travel the role requires. A preference is not a requirement. If you could train it or work around it, do not make it a knockout.

Keep the list short

Three to five questions is plenty. Every extra question lowers the number of people who finish. Put the most important ones first.

Word them neutrally

Ask whether the person can do the duties and meet the requirement, not about the characteristics that might explain it. Avoid questions about age, health, family plans, religion, origin or marital status. Laws on what you may ask differ by country, so check local rules.

Flag, do not reject

A required answer of no is a prompt for a person to look, not an automatic rejection. Candidates misread questions, and some requirements have exceptions. A person can see context a rule cannot.

Be honest about pay and shifts

Asking for pay expectation is useful when the range is tight, but say the range in the posting. Hiding it wastes everyone's time and can disadvantage people less willing to negotiate.

Tell candidates what happens with their answers

A short data notice, saying who sees the answers and how long they are kept, builds trust and is expected under privacy laws such as the GDPR.

In Rezumz

An open job gets its own application page. You write up to five questions, candidates answer and agree to a data notice, and a required answer of no flags the candidate for you to review. Nobody is rejected for you.

Frequently asked questions

How many screening questions should I ask?

Three to five. More lowers completion without improving the shortlist much.

Can I automatically reject candidates who answer no?

It is safer not to. Flag them for a person to review, because misread questions and exceptions are common.

Are salary questions allowed?

Rules differ by country and some places restrict asking about pay history. Asking for expectations against a stated range is generally easier to defend. Check local rules.
