Tell me about a time when you uncovered a significant problem in your team.

On my first team, I noticed that new engineers kept getting stuck during local setup, and at first I assumed it was just normal onboarding friction. After I compared notes with another recent hire, I realized we had both lost almost two days on the same broken step, so this was a real team problem. I reproduced it from a clean environment, documented exactly where it failed, and shared that with the engineer who owned the tooling. We found that one setup script had changed but the onboarding guide had not, so I helped update the guide and tested it with another teammate. After that, the next person joining the team got through setup in a few hours instead of over multiple days. What I liked about that experience was learning to verify that something is a pattern before raising it, and then helping close the loop instead of just flagging it.

At a small mobile startup where I worked, I kept seeing the same customer crash show up in our support queue after every release, but the developers couldn't reproduce it locally. I pulled together the CI logs, crash reports, and a few user session recordings and discovered the crash only happened when the app tried to load remote content on slow connections. I wrote a minimal test that reproduced the problem by throttling the network, then implemented a mock network layer in our tests and added a CI job that runs under the same throttling conditions. I also proposed a short checklist for testing network-dependent features and helped the team apply it to the next sprint. After those changes, the crash stopped appearing in releases and customer complaints went down noticeably.
