Google Data Science interview questions

Recruiter was really helpful throughout the whole interview process. The interviewer was also very professional and helped me calm down during the interview. The questions themselves are not that unique or different from questions you would get from other companies but it seems like their bar for the answers/performance is quite high.

HR connected me on LinkedIn. Two round phone interviews followed by an onsite interview. There are 4 interviewers, and the most challenging questions are about their product. They seem like open questions, but in fact there are correct answers and you must find it.
