4. Can you walk us through a challenging bug you encountered and how you resolved it?

This question tests your problem-solving skills and resilience.

How to Answer

Describe the bug, your troubleshooting process, and the final solution.

Example

"I once faced a critical bug in a data processing pipeline that caused data loss. I started by reviewing the logs and tracing the data flow. I discovered that a race condition was causing the issue. I implemented locking mechanisms to ensure data integrity, which resolved the problem and improved the system's reliability."

5. What is your experience with Agile methodologies?

Understanding Agile practices is important for collaboration in a team environment.

How to Answer

Share your experience with Agile practices, including any specific roles you have taken on.
