Patni Computer Systems Engineering interview questions

The Interview that I faced was challenging and it was an HR cum technical interview. They ask you questions mostly based on your final year project and since my branch was Electronics and telecomm., I was questioned on some subjects like microprocessors and microcontrollers. An unexpected question that I faced was, 'How would you implement your final yr project in a business model?' which stumped me but I managed to give him a satisfactory answer. And I was finally selected by them. They took 121 candidates from 2700 people.
