What is this question about
Interviewers use this question to assess whether you can actively grow other people rather than just complete your own work. They want to understand how well you diagnose someone's needs, tailor support, and follow through to a meaningful outcome. At higher levels, this also tests whether your approach to development scales beyond ad hoc mentoring into team health, retention, and organizational capability.
“Can you describe a time you helped someone on your team grow?”
“Tell me about someone you coached or mentored and what came of it.”
“What's an example of you developing a less experienced engineer or manager?”
“Have you ever deliberately helped an employee prepare for a bigger role? Walk me through that.”
“Give me a specific example of how you supported someone's career growth.”
Key Insights
- You should make the other person's growth the center of the story, not your generosity. Strong answers show that you understood what they needed, not just that you spent time with them.
- Don't stop at 'I gave advice' or 'we had regular 1:1s.' Show how you identified the gap, chose a development approach, adjusted when needed, and observed real progress.
- You do not need a heroic mentorship story. A credible answer often involves sustained, practical investment over time: creating opportunities, giving direct feedback, building confidence, and measuring growth through changed behavior or expanded responsibility.
What interviewers probe atlevel
Top Priority
You do not need a formal development plan, but you should show repeated, intentional support rather than a one-time favor.
Good examples
🟢I set up a short weekly check-in, shared how I broke down similar tasks, and gradually had them explain their own plan before I jumped in with suggestions.
🟢I first paired with them on one task, then asked them to lead the next small change while I reviewed their reasoning afterward so they could build confidence.
Bad examples
🔴I answered their questions whenever they messaged me, and that was basically how I mentored them.
🔴I walked them through the task once and then expected them to apply the same approach on future work.
Weak answers rely on availability; strong answers show a deliberate sequence of support that helps the person become more independent.
Even at junior level, you should show some concrete sign that your help changed the person's behavior or confidence.
Good examples
🟢By the end of the project, they were breaking tasks into smaller steps on their own and only coming to me for edge cases instead of every next step.
🟢On the next assignment, they led the implementation and explained the plan clearly without needing me to drive the work.
Bad examples
🔴They appreciated the help and said it was useful, so I felt like it worked.
🔴After I helped them, things seemed smoother and we didn't really have the same conversation again.
Weak answers rely on gratitude or vague impressions; strong answers show observable change in capability or independence.
Valuable
At staff level, taking over is especially costly because it can block the emergence of other technical leaders.
Good examples
🟢I stayed intentionally in the background during cross-team discussions so they could build credibility, and I only intervened when there was a material risk of misalignment.
🟢I coached them privately on framing and tradeoffs, then let them carry the decision publicly so others would see them as the owner.
Bad examples
🔴I represented them in the important cross-team conversations so the work would be well received while they focused on the technical details.
🔴I gave them ownership of the initiative, but I still acted as the final voice in most decisions to keep quality high.
Weak answers preserve your status as the real owner; strong answers deliberately create space for the other person to be seen and trusted.
Even small mentoring stories are stronger when they show care for the person's learning, not just finishing the assignment.
Good examples
🟢I wanted them to understand the reasoning so they could apply it later, not just copy my fix for that one issue.
🟢I spent extra time explaining how I approached debugging because they said that was a skill they wanted to build beyond this task.
Bad examples
🔴I helped them mainly because I needed their part done so my work wouldn't be blocked.
🔴I taught them the quickest way to finish the task so the project could stay on schedule.
Weak answers treat development as a means to your own delivery; strong answers show interest in the other person's durable growth.

Great answers
During my internship, a newer intern on a shared project was getting stuck a lot and was hesitant to ask questions in our team chat. I checked in with him and learned that the hardest part wasn't the coding itself, it was understanding how our team broke work into small steps and when to ask for feedback. I started doing two short check-ins each week where we would look at his plan before he started coding, and I showed him how I wrote down assumptions and open questions. After a couple of weeks, I asked him to lead the planning for a small task while I just reviewed his approach afterward. By the end of the internship, he was picking up similar tasks on his own and coming to me with specific tradeoffs instead of just saying he was blocked. That felt like real development because he was noticeably more confident and independent, not just unblocked for one task.
At my last job I noticed a new QA engineer wanted to learn how to write automated tests but was intimidated by the codebase. I volunteered to put together a six-week learning plan with tiny, hands-on exercises and we did two one-hour pairing sessions each week where I walked them through reading the repo, writing a simple test, and running it in our CI. I also gave them short homework tasks that built on the sessions so they could practice independently and asked them to pick one real bug to write an automated check for. By the end of the six weeks they’d authored their first end-to-end test, which actually caught a regression before release, and they were confidently contributing to the test suite. It felt rewarding because I helped remove a barrier between teams and gave a teammate a practical new skill that improved our product quality.
Poor answers
One time I invested in another intern's development by helping them a lot during onboarding. They were new to the codebase, so whenever they had a question I would answer it right away and often show them exactly how I would do the task. I also sent them some internal docs that I thought were useful. They ended up finishing their work, and they told me they appreciated how responsive I was. I think that was a good example of mentoring because I was always available.
