Contacted by internal recruiter. Followed by two technical phone interviews and onsite. General hiring. All interviews come with a pair of interviewers; sometimes one of them is a shadow. Technical phone interviews are all algorithm questions. Onsite interview consists of 5-6 rounds; 2 design, 3 coding/algorithm, 1 behavioral. HR is very professional. Overall employees have high spirit. You got a gift basket containing your LinkedIn social map and some snacks; you'll need them at the end of the day.
