Google

The HR found me on LinkedIn, then I contacted her via email. The first round was a short talk with HR about my graduation date, background, etc. Then came a phone interview. I failed the first phone interview, but the HR added another round for me.

I was contacted by a recruiter. After several emails with the recruiter, I had a brief (20-minute) chat with her. This was followed by one phone interview and then four onsite interviews.

I had two phone interviews with Google. The interviewers asked me about my research topic and how it could be associated with Google products. They also asked me to write code for a coding question, which I think was related to geometry.
