Opera Solutions Junior Analyst interview questions

Opera Solutions came to our college as part of the college placement drive. First round was shortlisting of candidates based on Resume. Second round was a 60 mins aptitude and logical test. The selected candidates were then interviewed a few days later. There were 3 interview rounds. First one was kind of technical/guesstimates interview. They were asking few technical questions and even some unrelated questions to put you in a stressful situation and see how you handle it. It was an elimination round. Second interview round was a quick HR round and wasn't an elimination round. The third and final round was an overall interview round with technical, HR and other kind of questions. In the interviews it seemed as if they already had made their mind and weren't in a mood to take many people. So they were rejecting and eliminating people even after good interviews and for bizzare reasons.
