TL;DR

I helped a teammate who was new to our API patterns implement a paged list endpoint. Instead of taking the task over, I walked through the existing endpoint style, explained the request DTO, validation, filtering, sorting, and response shape, then let them implement the first version. I reviewed the PR with comments focused on the pattern and the reasons behind it, not just the exact code changes.

Practice focus

Why this question matters
Mentoring is not only formal leadership. It is a practical signal that the candidate makes the team better, not just their own tickets.

Use this as an adaptable model, not a story to claim as your own. Replace the project, constraints, your actions, collaborators, outcome, evidence, and reflection with truthful details from your experience.

Stronger answer
Optional upgrade with examples, trade-offs, and sharper phrasing.
I tried to balance support with ownership. We paired on the first tricky part: avoiding arbitrary sort fields and keeping pagination stable. After that, they handled the rest and came back with specific questions. I also pointed them to a similar endpoint and wrote down a small checklist for future list APIs. That helped the current task and created a reusable onboarding note. I made sure the final implementation still belonged to them, because the goal was confidence and ownership, not only a merged PR.
