I applied through an employee referral. I interviewed at TikTok
Interview
1 hour interview. 45 min resume deep dive and 15 min coding. A lot of questions about Transformers were asked. The coding question is medium level in leetcode. Questions are progressive and I felt the interviewer was thinking about my experience carefully.
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.
