I applied online. The process took 3 weeks.

There were 4 rounds in total: 2 coding rounds, 1 behavioral, and 1 system. It was one coding problem per round; the problems were not too difficult but had a lot of follow-up questions. Behavioral is just standard questions. The system design round was also very standard.

Come up with a data structure to store movie ratings, where the rating of a new movie is calculated as an average of other movies in the same category. Include a method to add new movies and update its rating.
