Three rounds of interviews, technical interviews given through hacker rank and observed through zoom. About an hour in length, 2-3 problems given in that time frame and judging your performance.
Interview questions [1]
Question 1
What are the different approaches to solving this problem and what are the runtimes?
I applied, and then I was sent an online coding challenge of three questions on Hacker Rank. You have 120 minutes to complete them. I had about 96 hours to complete the assessment once I received the email for it.
I applied online. I interviewed at TikTok (San Francisco, CA) in Oct 2020
Interview
Overall smooth. Interviewer asked about resume and data structure. Relatively easy question about linkedlist and binary trees. Followed up on trie. The offer could be competed and I got some salary raised.
