“How would you handle a team member who is underperforming?” is a situational question. The interviewer is not asking whether you would act. They want to know how: in what order, with what evidence, how fairly, and at what point you would involve someone else. Most weak answers either jump straight to “I would raise it with HR” or stay vague (“I would have a chat and support them”).
This checklist gives you the steps a strong answer usually covers, based on how public-sector employers and employment advisers describe good practice. Use it to build a two-minute answer, then test your draft against the mistakes listed further down.
What the interviewer is scoring
Situational questions ask candidates to describe what they would do in a job-like scenario, and in structured interviews the answers are rated against benchmarks set in advance, according to the US Office of Personnel Management (OPM). For this question, those benchmarks typically reward four things:
- Fairness: you look for the cause before you judge the person.
- Directness: you raise the issue early and specifically, not after months of silent frustration.
- Follow-through: you agree a plan and check it, rather than having one conversation and hoping.
- Judgement about escalation: you know when the matter needs HR or a formal process, and you do not reach for it too soon.
The checklist: seven things a strong answer covers
1. Check the facts before you say anything
Start with what you would observe. OPM’s quick guide for supervisors lists signs such as frequent mistakes, low productivity, lack of initiative and disengagement. Your answer should show you would confirm the pattern with evidence: which deadlines were missed, which reports needed correcting, over what period. One bad week is not underperformance.
Acas, the UK’s workplace advisory service, also points out that a problem can have an underlying cause, such as illness or a disability, that changes how it should be handled.
2. Consider the cause
Acas’s guidance on capability says that if there are problems with someone’s performance, employers “should try to understand why.” OPM’s guide suggests asking whether the problem comes from a skills gap, personal circumstances, low motivation or the work environment.
Saying this out loud in an interview matters, because the fix depends on the cause. A skills gap needs training. Unclear priorities need clearer instructions. A personal problem may need flexibility or a referral to support services. A behaviour issue, such as repeated lateness, is a conduct matter rather than a capability one, and Acas treats the two differently.
3. Raise it privately, early and specifically
Both OPM and Acas recommend a private conversation focused on observable behaviour rather than personality. In your answer, name one or two concrete examples you would use and the effect on the team, then say you would ask for their view before proposing anything.
Keep this step short in an interview. How you word the feedback is a separate question; one sentence is enough here.
4. Agree clear expectations and a plan
The outcome of the conversation should be specific: what good looks like, by when, and how progress will be checked. OPM’s guide says goals “should be clear, detailed, and measurable.” Saying you would build the plan with the employee, not hand it to them, signals that you expect them to own it.
5. Offer real support
Support is the step candidates most often wave through. Be concrete. Acas lists coaching, mentoring and training as options for capability issues, and notes that where a disability is involved, reasonable adjustments should be considered before any disciplinary action. You might mention pairing the person with a more experienced colleague, removing a lower-priority task for a month, or arranging a specific course.
6. Follow up and keep a record
Say how often you would check in, for example weekly for the first month, and that you would recognise improvement when you see it. Both OPM and Acas advise keeping a record of performance conversations and the support offered. Mentioning documentation shows maturity; it protects the employee as much as the organisation, because it shows they were given a fair chance.
7. Know when to escalate
Finish with what happens if nothing changes. Acas says a performance improvement plan (PIP) can be used if informal steps fail, with specific objectives, a reasonable timeline and the support needed. OPM’s guide says a federal PIP will normally span 30 business days, though timescales vary by employer and country. The principle in OPM’s guide is useful to quote in spirit: corrective action comes only after support and clear feedback. Say you would involve HR at this point and follow the company’s procedure.
Putting it into a two-minute answer
You do not need all seven steps at equal length. A practical split is about 20 seconds on facts and cause, 30 seconds on the conversation and plan, 30 seconds on support and follow-up, and 15 seconds on escalation. Then, if you have one, add a short real example using the STAR method (situation, task, action, result), because a real example is more convincing than a hypothetical.
Illustrative answer: first-time team leader
“First I would make sure it really is a pattern. I would look at the last few weeks of work and note specific examples, such as missed deadlines or corrections needed. Then I would think about likely causes: are they new to this kind of task, are priorities clear, has something changed for them?
I would talk to them privately, describe two or three specific examples and how they affected the team, and ask how they see it. Together we would agree what needs to change and by when, and what support would help, whether that is training, pairing with a colleague or clearer instructions from me. I would check in weekly and say so when things improve.
If there was still no progress after a fair period, I would speak to my manager and HR about the next step, which might be a formal improvement plan.
In my last role I coordinated a four-person events team, and one member kept missing supplier deadlines. When we talked, it turned out she had never been shown the booking system. One hour of training and a shared checklist fixed it within two weeks.”
This example is illustrative. Replace the story with one of your own.
Illustrative answer: experienced manager
“I treat it in stages. Before I raise anything, I check the evidence and whether I have contributed to the problem, for example by changing priorities without explaining them. Then I have a private, specific conversation and ask questions before I give conclusions, because the cause decides the fix.
We agree two or three measurable expectations with a date, the support I will provide and how often we will review. I write a short note of what we agreed and share it with them. Most cases are resolved at that stage.
If they are not, I bring in HR and move to a formal performance improvement plan, following the company’s procedure. I have used that route twice in six years. Once the person improved and stayed. The other time we agreed together that a different role suited them better.”
Again, this is an illustrative model; use your own facts and numbers.
If the underperformer is a peer, not your report
Some interviewers ask this question of candidates who are not applying to manage people. In that case, do not describe actions you would have no authority to take. A good peer answer covers:
- speaking to the colleague directly first, about the specific work that is affected, and offering help if appropriate;
- adjusting how you work together, for example earlier handovers or a shared tracker;
- raising it with your manager if it keeps affecting deadlines or quality, framed around the work rather than the person.
Mistakes to check your draft against
| Mistake | Why it costs marks | Better |
|---|---|---|
| “I’d go straight to HR.” | Suggests you avoid direct conversations. | HR comes in after informal steps, or immediately only for serious conduct issues. |
| “I’d motivate them.” | Too vague to score; assumes the cause. | Find the cause, then match the response to it. |
| Describing the person as lazy or difficult | Judges character, not behaviour. | Describe observable work: deadlines, errors, output. |
| No follow-up | One conversation rarely changes performance. | Name a review rhythm and what you would track. |
| Doing their work for them | Hides the problem and burns you out. | Short-term cover only, with a plan to hand it back. |
| Sharing confidential details about a real person | Raises questions about your discretion. | Keep stories anonymous and leave out health or personal details. |
Preparing your example
If you have managed or coordinated anyone, write down one case where someone’s work improved after you intervened. Note the evidence you used, what you found the cause to be, what support you gave and the measurable result. If you have achievements like this, they also belong on your CV; the resume examples show how managers phrase people-development results in a single line. And if you are moving into a first management role, it is worth reading the job description for clues about the team’s size and the support structures in place, such as an HR business partner or a formal appraisal cycle, and mentioning them in your answer.
For HR-specific roles, interviewers will expect more detail about procedure; if you are applying for one, the HR manager resume builder can help you put that procedural experience on your CV.
Frequently asked questions
What if I have never managed anyone?
Answer as the person you would be in the role, and draw on what you have done: leading a project workstream, supervising interns, coordinating a student team or covering for a team leader. Be honest that you have not run a formal performance process, then show that you know the sequence: find the cause, be specific, agree a plan, follow up, involve HR if needed.
Should I mention a performance improvement plan by name?
Yes, if you can explain it properly. A PIP is a recognised next step when informal support has not worked, and naming it shows you know how organisations handle this. Do not open with it. Leading with formal action suggests you skip the conversation stage.
Is it acceptable to say the person was eventually let go?
It can be, if the story shows that you gave clear expectations, real support and a fair timeline first, and that you worked with HR on the outcome. Interviewers are wary of candidates who treat dismissal as the first tool, not of candidates who have had to reach it.
How is this different from “Tell me about a time you gave difficult feedback”?
The feedback question is about one conversation. This question covers the whole process: noticing the problem, finding its cause, the conversation, the support, the follow-up and what happens if nothing changes. Spend no more than a sentence or two on how you phrased the feedback itself.
