What is a qualifying question in recruiting?
Quick answer
A qualifying question, also called a screening or knockout question, is a short question tied to a requirement the job cannot do without, such as a license, the right to work in the country or a specific type of experience. A wrong answer usually ends the application or moves the person down the list.

Why it matters for a small business
It puts the one check you would make first on every resume at the front of the process, so nobody spends a call finding out the person has never done the core work.
Good questions are also fairer than gut feel: everyone is asked the same thing, the answer is recorded, and you can explain why someone moved on or did not.
The risk is overusing them. Each extra knockout removes people, and questions about nice-to-haves quietly shrink the pool below what the job needs.
In a real lesson: Pin: Check the Market and Set Up an AI Candidate Search for Recruiting & HR
In the Pin staff accountant search lesson the last Job Position card is Qualifying Questions. You add one yes-or-no question about real work, press Enter after it, and click Continue.
In the shortlist lesson that question is answered first on every candidate card, before the other criteria, with the evidence Pin found. When an answer starts with "Probably", Pin is inferring it from the title and firm, and it becomes a question for the call.

Common confusions
Qualifying question vs interview question
A qualifying question is a gate before the conversation. Interview questions, ideally asked the same way in a structured interview, explore how someone works.
Recruiting vs sales qualifying
In sales, lead qualification checks whether a prospect can buy. In hiring it checks whether a candidate meets a hard requirement. Same idea, different side of the table.
Knockout vs preferred
A knockout ends the application. A preferred question only ranks people. Decide which each one is before the job goes live.
Tips
- Keep it to one or two, and only for requirements you would truly not waive.
- Ask about work done, not traits: "Have you run a full hiring cycle from posting to offer?" tells you more than "Are you organised?"
- Avoid questions about age, family, health or anything else the law protects.
- Reread answers a tool inferred; a guess is not a yes.

Frequently asked questions
- How many qualifying questions should a job have?
- One to three. Each extra question removes more people, so keep them for requirements you would never waive.
- Can a knockout question be illegal?
- It can, if it screens on a protected characteristic or asks for information employers may not use. Stick to job-related requirements and check local rules with HR or an employment attorney.
- Is a qualifying question the same as a screening question?
- Usually, yes: the names are used interchangeably. Some teams say knockout question when a wrong answer ends the application automatically.
