Tech Mahindra interview questions

The HR called me for a f2f round. He scheduled the interview in the morning around 11 AM Saturday, but he did not arrange the interview panel properly. Those guys were fighting as there were only few people to take the interview and they wanted to go home. So all of us (around 150 candidates) had to wait for so long.

Well, had to give a lengthy aptitude test to proceed for interview, which was very short, nothing much asked. Rejected me, saying I dont know much about controller. Funny thing is, interviewer never asked a single ques abt controller.
