Aspire Systems Software Trainee interview questions

First round was a written aptitude round consists of Aptitude & technical aptitude(C prog) total of 40 questions all are objective. About 50% students got selected. Then the second round held the next day at the company aspire systems(siruseri). I gone at 8.30am there for 9'oclk batch, they started second round only at 12'oclk for us. I got selected and they asked to wait for the third round in a hall. In that hall we waited there from 1'o clock to 7'o clk, and we were told not allowed to go to canteen because they may miss the count. It was a terrible interview experience of my life, and at 8'o clk(pm) i was called for third round, they gave me a program and i know the coding it was an easy one for me, I started to write and within 10 minutes the HR came saw my code(half wriiten) (not hearing any explanation from me) and said it's wrong, u can leave now and grabbed my sheet and wrote rejected in it. After waiting for 7 hrs I was not even given enough time like others(45 mins for 3rd round) to finish my program as that HR wanted to go home bcoz it was getting late. So guys, once they reached the count of students they want to recruit, they dont even consider ur profile even ur profile is too good for them.
