In total there were 4 rounds, 1 machine test and the other 3 were technical interviews. I was applying as a fresher(right out of college). I was told to come at 12:30. I left the place at 5:45. They didn't told me that I was not selected right on my face. When I even mailed them to tell me some of shortcomings they didn't reply. The system they gave me for machine test kept on freezing. The allotted time was 45 to complete 3 questions. Once you are done, you also have to explain how you did it. The person who took my first interview was quite nice and supportive, the second person was a great man he gave time and answered my query regarding his question and also gave his introduction first and offered me coffee too. Third person was quite busy with his phone.
