When does a candidate screening question add useful evidence?
A screening question adds value when it asks for job-related information that the CV is unlikely to contain and when the team knows how the answer will affect the next step. Good questions close a defined evidence gap. They do not ask candidates to rewrite their work history or perform an unpaid essay exercise without a clear purpose.
For a role with rotating night shifts, availability for the agreed pattern may be necessary and absent from a CV. For a role requiring a current licence, asking for the licence type and expiry may resolve a real entry condition. “Tell us why you are amazing” usually lacks the same decision link.
What necessity test should every question pass?
Publish a question only when all five tests pass:
- Role relevance: the answer connects to an approved requirement or practical condition of the role.
- Information gap: the same information is not already requested or reliably available in the CV or application.
- Defined use: the team can state how the answer changes a gate, clarification, or later assessment.
- Proportionate effort: the requested detail is no longer or more sensitive than the decision requires.
- Safe handling: access, retention, and reviewer use are appropriate for the information collected.
The GDPR principles in Article 5 require personal data to be collected for specified purposes and limited to what is necessary. That principle supports a simple editorial rule: if the team will not use the answer for a defined recruitment purpose, remove the question.
Is the answer a hard gate, clarification, or interview material?
Choose the treatment before candidates respond:
| Treatment | Use it when | Example | Reviewer action |
|---|---|---|---|
| Hard gate | A lawful, confirmed entry condition must be met before the role can proceed | “Do you hold the current licence required to operate equipment X?” | Verify the answer and apply the approved condition consistently |
| Clarification | A short factual answer closes a material gap but needs context | “Which shifts can you work during the first six months?” | Compare with the actual schedule and clarify ambiguity |
| Interview material | The answer provides an example worth exploring, not a pass/fail fact | “Describe one production change you personally helped implement.” | Use the response to prepare structured follow-up questions |
Country-specific rules for work permission, health, disability, equality, and other personal information vary. Treat examples as prompts to verify locally, not universal legal advice.
Which questions add evidence instead of repeating the CV?
Useful examples include:
- Availability: “The role includes two night shifts every second week. Which parts of this pattern can you work from 1 October?”
- Certification: “Which current forklift certification do you hold, and when does it expire?”
- Location or travel: “The role requires on-site work in Odense three days each week. Can you meet that arrangement?”
- Role-specific evidence: “Describe one machine changeover you personally planned. What was your responsibility and what changed?”
- Work permission: ask only the locally approved, necessary question for the role and jurisdiction; do not improvise nationality questions.
The CIPD selection guidance supports structured, job-relevant selection. Ireland's Publicjobs interview advice describes structured interviews in which candidates are assessed against competencies or capabilities relevant to the role so assessment is equal and transparent. A short application question is not an interview, but the same evidence principle applies: tie it to a defined role requirement and decide how the answer will be assessed.
How can weak questions be rewritten?
| Weak question | Problem | Better question |
|---|---|---|
| “Tell us about your experience.” | Repeats the CV and has no evidence target | “Describe one production change you personally implemented and your role in it.” |
| “Why are you the perfect fit?” | Invites a vague sales essay | “Which of the role's three core responsibilities have you performed most recently? Give one example.” |
| “Are you flexible and resilient?” | Uses subjective labels without observable evidence | “The schedule changes with seven days' notice twice per quarter. Can you work under that arrangement?” |
| “Do you have certification, transport, availability, and five years of experience?” | Combines several decisions into one answer | Ask only the necessary unresolved condition, or separate the questions in systems that support more than one |
| “Rate your leadership from 1 to 10.” | Produces an unsupported self-score | “Describe a disagreement you resolved while leading an operational change.” |
Write the expected evidence and reviewer action beside the question. If those fields are blank, the question is not ready.
What does a worked question design look like?
Start with the approved requirement: “Can independently lead a documented safety handover after onboarding.”
The CV usually lists roles but may not show the person's responsibility in a handover. A focused question is:
Describe one safety handover you personally led. What information did you verify, who received it, and what record was created?
Expected evidence includes the candidate's own responsibility, the information checked, the recipient, and the record. A concrete answer becomes interview material. A vague answer triggers clarification; it should not silently become proof of inability. If the requirement is not genuinely needed at entry, do not turn the question into a hard gate.
How much effort should the candidate be asked to provide?
Use this candidate-effort checklist:
- The question closes one named evidence gap.
- The answer is not already available in the CV or another required field.
- One concise response is enough.
- The prompt avoids unnecessary sensitive or jurisdiction-dependent information.
- Candidates know the practical context needed to answer.
- Reviewers have an agreed use for the response.
- A missing answer is handled as missing evidence unless a confirmed entry condition says otherwise.
- The question will be removed if the team stops using its answer.
Skilltage guidance: choose one high-value opening-specific question rather than a long form. Skilltage currently supports one custom application question per opening and shows the candidate's answer during review. It does not provide a question bank, multiple custom questions, automatic answer scoring, or an automatic eligibility gate.
What are the limitations and decision boundaries?
A well-written question does not prove that a selection process is fair, lawful, or predictive. Candidates differ in writing style, language confidence, access needs, and time. A response may warrant clarification rather than comparison, and some capabilities are better assessed through a structured interview or work sample.
Do not ask for personal information merely because it might be interesting. Verify jurisdiction-specific rules before asking about work permission, health, family, criminal records, salary history, or other sensitive subjects.
First define the requirement and acceptable evidence. When software helps organise the answer, preserve human control and visible uncertainty.
Next step
Review every question in your current application form. Beside each one, write the requirement it supports, the evidence expected, and the action the answer can change. Delete any question that cannot complete all three fields.
