Use the STAR method (Situation, Task, Action, Result). Focus on Technical capability, Leadership, Impact, and Potential. Example: 'I worked on a NodeJS backend... updated test suite to run faster... saved time...'
Describe a complex issue, how you investigated it (logs, reproduction steps), the impact of finding it, and how you verified the fix.
Example: 'I am direct but kind. I act as a mentor. I bridge gaps between developers and stakeholders, ensuring clear requirements and feedback.'
Focus on resolution and professional growth. Example: 'A lead QA didn't want to share knowledge. I asked publicly in a group chat to encourage collaboration, which eventually broke the silo.'
