My first interview lasted for around 35 mins in which interviewer asked to code 2 questions based on normal arrays and strings. Another interview was Competetive coding in which interview did coding on his own and asked me to change his code . It was a binary search question and then he asked about my projects and research work. Last round was HR based but it was different for everyone . My other friends were asked to code in HR interview so they had basically 3 rounds of technical interview. But for me it was HR round only
