Have you ever had to read code and logs? For what purposes?

Yes, I have had to read and analyze code and logs for various purposes:

• Debugging: analyzing logs helps understand where and why an error occurred.
• Performance optimization: studying code and logs reveals bottlenecks.
• Security audit: checking code for vulnerabilities and analyzing logs for suspicious activity.
• Understanding someone else's code when joining a project or maintaining it.
• Verifying the correctness of new features through logs.

For example, when investigating a service crash, I examined logs to find the sequence of calls and identify the error, then looked into the code to understand how to fix it.
