First there was a qualifying round on hackerearth. It had 3 programming questions and some MCQs about data structures, operating systems and networking. The programming questions were really good with tight constraints. After that there were 2 rounds of interviews on skype. The first round focused on data structures and algorithms, technologies and computer science fundamentals. I was asked to code my solution for the algorithm questions. After clearing this round, I got a call for the second round. The second round focused heavily on the knowledge of operating systems, networking and database. It was really a difficult one.

1. First round had 5 programming and 10 technical mcq held on Codeground. 2. Next round was a telephonic interview 40-45 mins which focussed mainly on data structures, computer networks, 1 puzzle and OOPS. This round was mainly resume based. 3. Next was a f2f technical interview which went on for around 1hr . It had many questions related to data structures(linked lists mainly), conceptual questions related to CN, OS, C++(OOPS). And some easy puzzles. There was another f2f technical interview for which i didn't qualify.
