It was not tough if you knew your concepts. The interviewer was calm and made sure that I felt okay while giving the interview. The whole process was smooth and took like a week to get over with.
There are about 7 rounds to go through campus recruitment. Rounds range from a standard online questionnaire/coding to multiple technical and human resources rounds. Doe to this, may be a longer process, but the interview/other rounds are not very difficult.

Interview
First round was assessment round which had 90 questions including 2 easy coding questions.Other questions were on Java,OOPS,Aptitude,Hadoop,Cloud etc.It was overwhelming.
Second round was technical interview.The interviewer was very friendly.She asked questions related to what you know and on the projects that you have worked on.Even if you dont know the answer,atleast try to answer as best as you can.That doesnot mean that you can get away without properly answering anything.
Third round: A senior employee will be interviewing you.I wont call this an HR interview.The questions he asked was nor technical neither behavioural.But you can answer them if you know everything in your resume.
