I applied online. The process took 3 weeks. I interviewed at TikTok (London, England) in Mar 2022
Interview
There were 3 stages, first two were coding + ML questions. The interviewers were helpful and friendly. When l stuck, they were giving hints about the questions. In the second stage, l was able to use only one library function. The last stage was with manager/leader who wanted to hear more about the research that l am doing.
