5 rounds of medium to hard level questions and one behavioral. Each round features a different interviewer from different teams and orgs. You get one break among all the interviews.

I had two 45-minute phone overviews and one 45-minute in-person technical interview.

The interviewer was a Chinese girl, and her English was too poor to understand. The interview question was about System Design, like YouTube search. She was not clear, so I kept asking her to repeat.
