I applied through a recruiter. The process took 2 weeks. I interviewed at TikTok (San Jose, CA)
Interview
Hr call and Hacker Rank Interview and machine learning algorithms. The interview lasted about 1 hour and 30 minutes and the interview was scheduled with the HR. The response time and decision took exactly one week which was very fast compared to other companies.
Started with a recruiter screen with simple checks. Then went through 3 rounds of interviews. First 2 rounds were live coding with deep dive on previous projects. 2nd round went really deep of every previous work I did from MLE perspective with being questioned of every possible decision choice. Last was interview with team manager.
