Referred from inside, got a phone interview then followed by another phone interview and 1 other skype interview. The first phone interview is somewhat like a personality test. The second one has more technical questions to answer, asked me about the basic data structures. The third one is a 4 person back to back interview, testing mostly manipulating data structures and applying algorithms on them .

4 rounds in total 1 was with end director about past exp 1 was code given and review, mainly security and other issues 1 was system design, a particular part of big system in detail 1 was code review but make it modular, performance, API calls etc
