referred by a friend, got a call from an recruiter after 2 days, then arrange a phone screen. Kind of easy question then got onsite invitation. 5 sessions in a day, 2 interviewers for each session. Three rounds are pure algorithm coding, one behavioral session in which 20 minutes about work experience and behavioral questions, then end with a coding question. One architect session. No that difficult, reply on how familiar with these asked questions. How good solution and how elegant code you can give. Got declined notification after 3 weeks later.
