TikTok Software Developer interview questions

First round technical interview was a medium Leetcode done live. The answer involved turning a nested loop into a looped binary search. We then moved on to a discussion of solving certain scaling and technical performance problems at the database and web layer.

First you apply and get an OA. If you score good enough (don't need perfect score), then you get the interview where they give you really hard questions. It depends on interviewer, but someone I knew got an easy string question.
