I applied online. The process took 3 months. I interviewed at TikTok in Jan 2024
Interview
First round. Two coding questions, leetcode 1863 and leetcode 76. First introducing their group then coding. 10mins self introduction and 50 minutes for the 2 coding problems. Solved them all and move to next round.
I was given an OA Interview, questions were not hard. They sent me a link for a website like HackerRank. One of my answers did not pass(TLE) and i was rejected. The only problem with the process is that they don't notify or send emails to reject you.
