Your focus will be on functional, usability, and compatibility coverage while validating data accuracy with targeted SQL queries against the live database.

An analytical eye that spots edge-case failures is more important than sheer speed. When you respond, highlight previous web-application projects you’ve tested, the databases you queried with SQL, and any QA toolchain you rely on—those real-world examples help me gauge...
