I applied online. The process took 5 days. I interviewed at TikTok
Interview
I took the screen and probably bombed it. According to others, there are two more technical interviews after the OA. Overall somewhat difficult problems, but you should be familiar with DP.
Interview questions [1]
Question 1
The OA involved five questions; two were multiple choice and the other three were easy-medium DP problems (Find minimum push_back operations to sort a list of numbers in increasing order, a House Robber problem, and a 0-1 Knapsack problem)
Applied online, got coding challenge consisting of 5 problems. The difficulty was average but you have to manage your time well. I managed to solve 3 out of 5 got an interview.
The OA was hard but manageable. The first few questions were recursion and then there was an OOD question about a data structure. There was a pretty hard question about 3D geometry DP but it was also managable.
