I applied online. I interviewed at TikTok (Londres, Angleterre)
Interview
Few rounds of technical interviews. first round leetcode and basic machine learning questions. the interviewer was nice and patient, helped when needed, felt like collaborative experience. second round interviewer seemed to be multitasking and was rude. did not make it through to 3rd round
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.
