I'd talk about the time I pushed for TypeScript adoption. The team was resistant because of the learning curve, but I created a gradual migration plan starting with new files only. After a month, bug reports dropped noticeably and the team bought in.

Good structure. You hit the situation, action, and result. Try to include a specific metric next time, like percentage reduction in bugs. Quantified outcomes make a much stronger impression.

10:07 AM

Let's move to a system design question.
