Concurrency questions trip up a lot of candidates because they don't know what to look for. In this video, I'll give you a framework that makes these problems predictable.
We start with a real bug (the kind that shows up constantly in interviews), then break down the three types of concurrency problems you'll actually encounter: correctness, coordination, and scarcity. Once you know these patterns, you'll know exactly what primitives to reach for.
