I applied online. I interviewed at TikTok in Feb 2025
Interview
The OA had two problems: one required implementing BFS, likely involving graph traversal, shortest path, or level-order processing. The other was related to binary trees, possibly dealing with traversal, recursion, or tree modifications like lowest common ancestor or subtree calculations. Both were quite challenging, requiring efficient algorithms and strong problem-solving skills.
Interview questions [1]
Question 1
Data Structure/ Algorithm/ Object Oriented Programming
2 rounds coding a lot of background questions very strange behavior from interviewer camera was off and asked questions in mandarin, leetcode medium-hard and very very slow communication from recruiters based in asia for an english role
OA - 1 arrays Medium, 1 Trie Hard. I had 45 minutes to complete that. I was able to do the medium in about 15-20 minutes but I am not that great with trie ds so I was not able to finish.
