Got OA after resume screen. Four LeetCode style coding questions that can be finished in either Python or C++; the last one is unlocked only when the third one is finished. Got 1200/1200 for OA but was rejected afterwards.

First round: There's only one big question. You have to come up with something, and then the interviewer asks you to implement a tiny simulation in Python where you run some experiments on the question you were just asked.
