1-Week Interview Sprint ("The Final Stretch")

The essential 7-day high-yield triage when your interview is just around the corner.

When you have an interview scheduled in 7 days, you need a ruthlessly prioritized, high-yield checklist. This sprint targets the exact topics asked in 80% of technical loops: event loop execution order, connection pool exhaustion, HTTP idempotency, database index traps, and core system design heuristics.
