It was a 4 round process after clearing the online assessment test which include very easy level 2 coding question one is on mainly some formulas based and other any random basic question. Among those 4 rounds, 2 were purely deep technical rounds and then there was a tech+hr round and after that, the last one was total hr round. The technical rounds require deep knowledge of networking, OS, and troubleshooting ( generally they mention the individual topics for the preparation of the interview in the mail around 1 week before the interview). I highly recommend to go through some good and standard books for the preparation instead of preparing through youtube videos or some random websites because they will really ask you each and every possible practical question based on that topics. I did this mistake of not preparing through the standard books which I really regret a lot that is why I am just suggesting it. Books will definitely help you and will give you a better understanding of that topic.
