I applied through an employee referral. The process took 5 days. I interviewed at TikTok in Jan 2024
Interview
The role was for software engineer (recommendation system machine learning engineer). It was a good interview and the questions were technical and situational both (by situational, I mean they were related to TikTok’s recommendation system).
