Request samples of prior MySQL implementations or schema designs. Review their proficiency with stored procedures, data normalization, and large-scale query optimization. The best developers understand both data architecture and the business logic behind it.

3. Key Interview Questions

What are the key differences between MyISAM and InnoDB storage engines?

How would you optimize a slow-running query?

Explain normalization and when denormalization might be beneficial.

How do you secure sensitive data in a MySQL environment?

Describe your approach to database replication and backup strategies.

4. Practical Test

Ask candidates to write SQL queries for complex joins or aggregation tasks and perform optimization on a large dataset. This evaluates real-world database handling, indexing strategy, and analytical problem-solving skills.
