TikTok Machine Learning Engineer interview questions

Recruiter screen then organised first technical interview. Told a few days before the role had been pushed into next quarter, then heard nothing subsequently. Reached out again and had the interview rescheduled to then be told 2 days before that it was cancelled as they didn't feel I had appropriate skills. Bit strange, felt symptomatic of a larger chaotic vibe I got from the company.

Online Assessment for first step of hiring process. The provided helper code had errors that needed fixing before any testing could be done, reducing the time allocated to actually solving the problems.
