What follow-up questions help clarify a vague interview answer?
Quick answer
Ask one neutral question at a time, starting with what the interviewee meant. If needed, invite a specific example, sequence, or detail, then reflect your understanding and let them correct it. For instance: “You mentioned it was difficult. What did ‘difficult’ mean in that situation?” Avoid offering your own explanation as if it were theirs; record any uncertainty rather than filling gaps yourself.
The question, the details, the next step.
Someone gives a vague answer in an interview, like “It was complicated.” What can I ask without steering them toward my interpretation?
Start by asking them to explain their own word, rather than suggesting what it might mean. Keep the probe short and open-ended, and ask just one thing at a time.
A compact bank, grouped by purpose:
- Clarify meaning: “What does ‘complicated’ mean in this situation?” or “Could you say a little more about that?”
- Invite an example: “Can you walk me through one occasion when that happened?”
- Find a specific detail: “What part stands out most?” or “What happened next?”
- Clarify sequence or context: “What was going on just before that?” or “When did you first notice it?”
- Check your understanding: “I heard you say [their words]. Have I understood you correctly, or would you put it differently?”
Treat the first answer as theirs, and your interpretation as a question—not a fact.
How do I choose between those? I don't want to ask a string of questions when one would do.
Choose the probe based on what is missing. If the word itself is unclear, ask what they mean by it. If you understand the word but need to see what it looked like in practice, ask for an example. If you already have an example but lack a useful detail, ask about one part of that event.
For example, after “It was complicated,” try: “What does ‘complicated’ mean in this situation?” Pause and listen. If the answer is still broad, follow with: “Can you walk me through one occasion when that happened?” That sequence asks for meaning first, then an example only if it is useful.
What if I think I know what they mean, but I might be wrong?
Make your guess easy to reject, and don't put it inside a question that assumes it's true. Instead of “Was it complicated because your team kept changing the plan?” try: “I may be interpreting that too narrowly. What made it complicated for you?”
If you need to check a possible interpretation, label it as yours: “I wondered whether the changing plan was part of it, but I don't want to assume. Was that relevant, or was something else more important?” This gives them room to disagree or introduce a different explanation. If they do, use their wording in your notes rather than silently substituting your guess.
Could you show me a short worked example and a way to keep the notes accurate?
Here is a hypothetical exchange:
Interviewee: “The handover was messy.”
Interviewer: “What does ‘messy’ mean in that situation?”
Interviewee: “I wasn't sure which version of the plan to use.”
Interviewer: “Can you walk me through one time that happened?”
Interviewee: “On Monday, I had the earlier plan, but the team was discussing a newer one.”
Interviewer: “So you had an earlier version while a newer one was being discussed. Have I got that right?”
The notes could separate the account from any interpretation:
- Interviewee’s words or close paraphrase: “Wasn't sure which version of the plan to use.”
- Example given: On Monday, had the earlier plan while the team discussed a newer one.
- Unconfirmed interpretation or open question: What caused the versions to differ? Not established in this answer.
That last line matters: don't write “poor communication caused the problem” unless the interviewee actually said that. A clarification answer can make one detail clearer without establishing the cause or the broader pattern.
A practical checklist
Identify what is unclear: a word, an example, a detail, or the sequence.
Ask one neutral, open question and give the interviewee time to answer.
Invite a concrete occasion only when an example would help.
Label your interpretation as tentative and make correction easy.
Keep the interviewee’s account separate from your inference in your notes.
A few more useful answers
Should I repeat the interviewee’s exact vague word?
Often, yes: repeating their word can make the point you want clarified clear without supplying a replacement. Ask what that word means to them in this situation.
What if the interviewee says they don't know or can't remember?
Accept that answer rather than pressing them to guess. You can ask whether there is another detail they do remember, or note that the point remains unclear.
How many follow-up questions should I ask?
Ask only what is needed to understand the point relevant to your interview. A meaning question followed by one example probe may be enough; don't treat the probe bank as a script to exhaust.
