How does Structured Concurrency handle cancellations and exceptions?
This tests scope-bound lifecycle management preventing leaks. Cover scope cancellation cascading to children, exceptions propagating up to cancel siblings, and launch or async requiring a scope. A red flag is treating coroutines as fire-and-forget threads.
This tests your understanding of Structured Concurrency as a scope-bound lifecycle guarantee that prevents leaked work. A strong answer explains three mechanics: cancelling a scope recursively cancels all child jobs, exceptions bubble upward and trigger sibling cancellation, and coroutine builders like launch and async are scoped so they cannot outlive their parent. A red flag is describing coroutines as global background threads without mentioning Job hierarchies or the difference between SupervisorJob and regular Job propagation.
