HR approached me through a referral. Interview scheduled within a week. 1 hour interview for the first round. Only coding questions were asked. Overall experience was great. Had learned a lot during the process.

Overall 4 technical rounds including Director/Manager round. First three rounds were of average difficulty including some array and linked list based questions. Some puzzles were also asked and situation based test cases also asked. In last round system design question was asked. All rounds took place on same day one after the other.
