I joined as fresher and for freshers it's easy to crack the interview. You should be clear with the basic fundamentals of your subject and be confident enough during the process.
There were mainly 3 rounds.
In first round was an OA round.it was focused on your logical thinking.
In second round it was based on dbms,apitude and some basic star patteen kind of questions.
And third one was HR round.
