Great discussion topic! Here are some tips that helped me with DevOps interviews:

SQL & Database Skills

Don't underestimate database questions in DevOps interviews. You'll often be asked about:

• Query optimization: Understanding EXPLAIN ANALYZE, indexing strategies, and query execution plans
• • Database operations: Backup/restore procedures, replication, and failover scenarios
• • Infrastructure queries: Writing queries to analyze logs, metrics, and system data
    Pro tip: Practice writing SQL queries under time pressure. Tools like ai2sql.io can help you understand query patterns and validate your SQL syntax quickly - useful for both learning and interview prep.

General Interview Tips

1. Hands-on practice: Don't just read - actually run the exercises in this repo
2. 2. Explain your reasoning: Interviewers care about your thought process, not just the answer
3. 3. Know your tools: Be ready to discuss the "why" behind tool choices (Terraform vs CloudFormation, etc.)
4. 4. System design: Practice drawing architecture diagrams and explaining trade-offs
      The exercises in this repo are excellent for structured preparation. I'd suggest grouping them by topic and doing mock interviews with peers.

Good luck to everyone preparing! 🚀
