I applied through college or university. The process took 2 months. I interviewed at TikTok in Nov 2022
Interview
Very fast, three medium leet code questions and some SQL questions with additional traditional machine learning algorithm like SVM, linear regression. Friendly interviewers, I learnt a lot from them. In overall I like the interview process.
