What is this question about
Interviewers use this question to assess whether you can meaningfully invest in other people's growth, not just give occasional advice. They want to understand how well you noticed someone's needs, tailored support to that person, and followed through long enough to create a real outcome. At higher levels, they are also testing whether your approach to career development scales beyond one-off mentoring into repeatable leadership behavior.
“Can you describe a situation where you helped someone on your team grow into their next role?”
“Tell me about a person you mentored or coached and what changed for them as a result.”
“Have you ever helped a teammate make progress toward a career goal? Walk me through that.”
“What's an example of you investing in someone else's development, not just their immediate project work?”
“Think of someone who grew under your guidance. What did you do, and how did you know it worked?”
Key Insights
- You do not need a promotion story for this to be strong. A compelling answer can be about helping someone gain confidence, broaden ownership, improve a weak area, or prepare for a next-step opportunity.
- You should show that you understood what that person actually wanted, rather than projecting your own idea of a good career path onto them. Interviewers notice the difference between mentoring and directing.
- Do not stop at 'I gave advice.' Strong answers show an ongoing loop: you diagnosed the need, helped create a plan, created opportunities or support, and then observed concrete progress over time.
What interviewers probe atlevel
Top Priority
Even at junior level, your story should include specific help you provided, not just encouragement.
Good examples
🟢I paired with them on their first task, showed how I broke the problem down, and then let them drive the next similar task while I stayed available for questions.
🟢I helped them prepare for a team demo by reviewing their draft, practicing with them once, and giving feedback on how to explain the tradeoffs clearly.
Bad examples
🔴I told them they were doing fine and that they should keep asking questions because that is how people improve.
🔴I suggested some articles and videos and considered that enough support for their development.
Weak answers are mostly verbal encouragement; strong answers involve practical, hands-on support that changed the person's experience.
At junior level, the bar is not formal mentoring; it is showing that you listened, understood what a teammate needed, and offered help that fit that need.
Good examples
🟢I noticed a teammate seemed hesitant in code reviews, so I asked what they were trying to get better at. They said the real issue was confidence explaining their changes, not the coding itself.
🟢Before helping, I asked whether they were trying to get faster technically or become more comfortable owning small features. That changed the kind of support I gave.
Bad examples
🔴They were new to the team, so I just showed them the way I usually do things and told them to follow that process because it worked for me.
🔴My teammate said they wanted to grow, so I encouraged them to take on more tasks. I did not really get into what kind of growth they wanted.
Weak answers assume help is generic; strong answers begin by understanding the person's actual aspiration or obstacle.
Valuable
Helping someone develop is not doing the work for them; it is making them more capable the next time.
Good examples
🟢I gave them a starting structure and answered questions, but I let them make the main decisions on the task so they could build confidence.
🟢When they asked me to rewrite part of their change, I instead walked through one example with them and then had them apply the same approach to the rest.
Bad examples
🔴My teammate was nervous about a task, so I mostly took over the tricky parts and then explained afterward what I had done.
🔴I wanted them to be successful, so I reviewed every small decision before they acted and stayed heavily involved the whole time.
Weak answers optimize for short-term output; strong answers preserve the other person's ownership so learning can happen.
As a junior candidate, choose a believable story about peer support or onboarding help rather than claiming full career ownership for someone else.
Good examples
🟢A more realistic example for me was helping another new engineer get comfortable with our team's workflow and speak up more during reviews.
🟢I focused on a small but real contribution: helping an intern build confidence and navigate their first few tasks.
Bad examples
🔴I basically mentored a senior teammate into a new level by telling them how to think about their role.
🔴I drove one of my teammate's career development by deciding what projects they should take and how they should grow.
Weak answers overclaim authority and impact; strong answers stay credible for the candidate's actual level while still showing helpfulness.
Example answers atlevel
Great answers
On my last team, a new engineer joined a few months after I did, and I noticed she was pretty quiet during code reviews even though her work was solid. I asked if she wanted feedback on anything specific, and she said the hardest part was explaining her decisions clearly, especially when more experienced engineers asked questions. I offered to review one of her changes with her before she sent it out, and we practiced how to write the summary and respond to likely comments. After that, I stayed available, but I made sure she was the one posting and answering the review comments herself. A few weeks later she told me she felt much more confident, and I saw that in practice because she was handling reviews on her own and even helping another new teammate with theirs.
At the startup where I worked, one of our part-time contractors wanted to convert to a full-time engineering role but hadn’t interviewed for software jobs before and felt lost about how to present their work. Over the course of a month I scheduled weekly pairing sessions where we worked on a small end-to-end feature they would own, and I taught them how to break problems into steps, write a short project summary, and pick demonstrable metrics. I reviewed their resume bullet points and helped them craft clear stories for behavioral questions, then ran two mock technical interviews with immediate, actionable feedback. I also encouraged them to lead the demo for that feature so they’d get comfortable presenting to stakeholders. They ended up being invited to join full-time, and their manager later told me their ability to plan and communicate had noticeably improved.
Poor answers
A teammate on my last project wanted to grow, so I showed him how I usually handled our tasks and told him that if he followed my approach he would ramp up faster. He had a lot of questions, so I often just fixed the tricky parts for him so we could keep moving. I also told him to take on more work whenever he had time because that is the best way to develop. He appreciated the help, and after that I felt like I had done a good job supporting his career.
