Tell me about a time you learned something new and applied it to solve a problem.

In my first few months, I was assigned a bug where a form would sometimes submit duplicate requests. I could reproduce it, but I realized I didn't really understand how our front end handled async state updates, so I spent a couple of hours reading the internal docs and tracing a similar component that was known to work well. I then built a small local example to confirm when the button state changed, and that showed me we were re-enabling the submit action too early. I updated the component, added a test for repeated clicks, and asked QA to rerun the original case. The bug stopped reproducing, and I used the same approach on another UI issue later, where breaking the problem into one concept I needed to learn first made me much faster.

At my previous job I inherited a nightly reconciliation job that was taking three hours and often failed, which forced the ops team to intervene every morning. I didn't know much about database performance, so I spent a day reading the vendor docs, ran the database’s query planner tool to inspect the slow SQL, and asked a senior engineer to review my findings. I recreated the problematic query on a smaller dataset, rewrote the joins to use a different aggregation pattern, and added an appropriate index. After deploy the job finished in about ten minutes and stopped failing, and I wrote a short runbook and a lightweight alert so we’d notice regressions. That workflow—identify, learn the tool, test locally, and then fix—has become my standard approach when I run into slow reports.
