Real World Problem Solving and Edge Cases Questions

Ability to solve practical problems that surface once a solution is actually built and running in the real world, not just in the happy-path design. Covers identifying and handling edge cases, working around system quirks and inconsistent or undocumented behavior, managing timing issues and race conditions, dealing with dynamic or unpredictable inputs, and choosing pragmatic tradeoffs when the textbook approach does not fit the constraints at hand. Also covers thinking through an entire execution flow end to end to anticipate where and how it can fail before it does.
