Concurrency & Parallelism Interview Questions | Python | NextRound

1How does Python's asyncio event loop achieve concurrency without using multiple threads?Advanced

2What is the difference between threading, multiprocessing, and asyncio, and when would you choose each?Advanced

3What causes a deadlock in multithreaded code, and how can it be avoided?Advanced

4Why does multiprocessing avoid the GIL problem, and what overhead does it introduce instead?Advanced

5Given the GIL, why can multithreading still improve performance for I/O-bound tasks but not CPU-bound tasks?Advanced

6What is the difference between async def and a regular function, and what does await actually do?Intermediate

7How would you run CPU-bound work alongside an asyncio application without blocking the event loop?Advanced

8What is a race condition, and how would you prevent one using threading.Lock?Advanced

9What is the Global Interpreter Lock (GIL), and why does it exist in CPython?Advanced
