3 Technical Assessments with an Engineer. I only did one round despite answering 1.5 of the questions correctly (ran out of time for the second one). The interviewer payed no attention to me during the assessment and was very rude.

I often do not give much weight to glassdoor interview reviews, but they were dead-on accurate for TikTok. Two rounds. Both had 30-45m of open questions followed by a leetcode easy coding question. The second interviewer arrived 5m late and started the coding part with less than 15m left. They stated we could "go over time", but I had to go, so never finished.
