TikTok Software Developer interview questions

First round was difficult hackerrank. Two medium to hard questions and 5 multiple choice having to do with computer science knowledge and code tracing. Next was onsite but dropped out because of mandatory 4 days in office.

I applied to the position. Then i got OA. after I finished it, I got interviews. 2 interviews in total. just leetcode, no other question. so be familiar with leetcode
