Describe a complex problem you solved

Behavioral questions

1. Complex problem : Tell me about a time you worked on a complex technical problem.
   • What made it complex (scale, ambiguity, cross-team dependencies, unclear requirements, etc.)?
   • How did you break it down, decide priorities, and drive execution?
   • What was the outcome and what would you do differently?
2. Using GenAI tools : How do you make use of generative AI tools in your daily engineering work?
   • What tasks do you use them for (debugging, code review, design docs, testing, data analysis, etc.)?
   • How do you validate correctness and prevent subtle errors?
   • How do you handle privacy/security concerns and team norms?

(Interviewers may ask follow-ups based on your projects: tradeoffs, impact metrics, collaboration, and lessons learned.)
