The process was very easy. We were told to deliver a presentation to the interviewers for which the format was already sent. In the presentation we had to choose our cluster preferences and other basics like Why do you want to join Maruti Suzuki, your expectations from the company etc.
After the presentations only one interview was there was like(Technical + HR interview).
They asked fairly simple questions from DBMS, OS, Data Structures. But they asked some really tough from the Networking. So you just need to prepare Networks very well, rest everything will be basic.
