Task
How the developer approached the problem, step by step. 🎯 Skill Signal = moments that reveal strong engineering habits.
Explored file tree, opened 4 files before first action
Opened main.go and handler.go, scrolled through connection pool logic
"Explain the connection pool lifecycle in this codebase and where leaks could occur"
Found pool exhaustion under load — connections not being returned on error paths
Asked AI to generate a defer-based connection release pattern
AI suggested releasing connection twice — candidate spotted the double-free bug and corrected it
13/15 passing — identified 2 edge cases still failing
"The timeout test is failing because the pool size is 5 but we're spawning 10 concurrent requests. Fix the test setup."
15/15 tests passing after fixing test setup and adding error path coverage
Re-read all changes, ran tests one more time, verified no regressions
