Browse 3 real-world technical and behavioral interview questions about Deadlock. Review scenarios, edge cases, and architectural best practices.
Python multiprocessing behaves differently across platforms because fork inherits parent memory while spawn starts a fresh interpreter, re-imports the module and requires picklable callables and arguments. It also connects start methods to the point an interviewer is testing.
A deadlock is a cycle in the wait-for graph, so the design goal is a graph that cannot contain one: stop holding two locks where you can, impose one total order on acquisition everywhere you cannot, and never call unknown code while holding a lock.
Blocking on async code with .Result or .Wait can deadlock when the awaited continuation needs the same SynchronizationContext that is blocked. In ASP.NET Core the common failure is thread-pool starvation; the fix is async all the way up.
