I applied through an employee referral. I interviewed at TikTok in Oct 2022
Interview
One month after application, received an invitation to OA with a 3 days window. After one week of 70 minutes OA, received a recruiter email to schedule the VO. The first VO is a technical coding challenge.
Interview questions [1]
Question 1
Two questions in the first round of VO. The first one is a difference array, the second is dp.
4 rounds. First OA, then 2 VO, with one coding question each, finally HM. HM round was actually no behavior question at all, but two leetcode medium questions instead. These questions are the most popular questions of BFS and backtrack.
First answered a few basic questions like self intro, pass experience, data structure etc. then did 2 leetcode problems with the employer live & dry run the program. asked if any follow up questions.
