Free Knockout Question Generator
Knockout questions are yes or no screening gates that check hard requirements (license, location, work authorization, availability) before anyone spends time interviewing. This generator turns a role's requirements into them, phrased so a candidate cannot misread them. Free, no signup, ATS-ready.
What is a knockout question?
A knockout question is a screening question with one disqualifying answer. It checks a requirement that is truly yes or no, before anyone spends time interviewing.
"Do you hold an active RN license in California?" is a knockout. "How many years of Python do you have?" is not. That one is a preference, and using it as a gate removes people who could do the job.
When should you use knockout questions?
- Legal and licensing requirements: work authorization, a professional license or a required certification.
- Practical requirements: a work location, a shift pattern, travel or an on-call rotation.
- Requirements set by a client or regulator, such as a security clearance.
Skip them for skills, years of experience and culture fit. Those need judgment, so they belong in screening criteria or an interview.

How to decide if a question should be a knockout
- Ask whether you would ever hire someone who gives the disqualifying answer. If you would, it is not a knockout.
- Keep the set to 3 or 4. Each extra gate removes people before a person reads their application.
- Ask about the requirement, not the person: authorization to work rather than citizenship, shift availability rather than age or family.
- Have HR or legal check each gate for every place you hire. Rules on age, health, criminal history and citizenship differ by jurisdiction.
- Look at who failed each gate once a month. If strong people keep failing one, it is probably a preference.
Compliance warnings
Some questions are unlawful to ask as gates in some jurisdictions, and the boundaries differ between them, around age, health, criminal history and citizenship in particular. The generator flags a question that commonly crosses a line and suggests a lawful phrasing that gets at the same requirement.
Screening is not assessment
Knockouts remove people who cannot legally or practically take the job. They say nothing about who is good at it. Screening criteria handle the judgement calls, and AI interviews assess capability for everyone who clears the gates.

Frequently Asked Questions
What are knockout questions
Knockout questions are early, often yes or no, must have screening questions such as work authorization or minimum years of experience, used to quickly filter out candidates who do not meet non negotiable requirements before a full interview.
How are the knockout questions generated
Based on the hard requirements of the role, such as certifications, work authorization, location or minimum experience, the tool generates a short set of qualifying questions to screen candidates early in the process.
Where in the hiring process should knockout questions be used
They are typically used at the application stage or during an initial phone screen, before a candidate is invited to a full interview, so you avoid interview fatigue from evaluating candidates who never met the baseline requirements.
Can knockout questions accidentally introduce bias or legal risk
If poorly worded, screening questions can raise compliance concerns, for example by indirectly probing protected characteristics. The tool is designed to generate questions based on legitimate job requirements as part of fair hiring practices, but you should still have questions reviewed by HR or legal for your jurisdiction.
How many knockout questions should I use
Generally as few as possible, covering only true must haves. Too many knockout questions can filter out strong candidates over minor or non essential criteria.
