Campus placements are conducted in 4 stages. Technical exam followed by two sessions of 3 member panel of interview and then at last an HR round. Technical rounds focus on your basic knowledge, where they check if your fundamentals are strong. A week foundation cant be used to build a high rise building and they check if you have what it takes to build your up to there requirements.

I was called by a recruiter telling me that I have a technical interview the next day. The technical interview was okay, there were two interviewers, they were very kind, and I really had a good time. I was not able to answer all the questions, however, they discussed the answers without making me feel dumb. After that was the final interview, it was also a technical interview, mostly about circuit analysis. I also had a good time.
