TikTok Software Developer interview questions

interviewer did not care about explaining code, focused on optimization to the extreme....question itself was easy to solve but optimization was hard, discussed the optimization strategies with the interviewer and he helped me figure out the best ways to optimize

Approached by HR. Two rounds of technical interview (online). Both interviews were about past experiences and asked specific questions about the tech used + 1 medium LC question in each round. The first interview was ok, although for some questions I'm not quite sure, algo AC. The second interview was bad/terrible, the interviewer could not give clear instructions and kept interrupting while I was speaking. He asked to go through certain things but then interrupt in the middle and rush to the next question. Algo AC but he doesn't seem to care. Overall a waste of time and effort, the feedback is total non-sense from the HR. If you do not want to hire then don't keep approaching people to waste their time.
