Tech Mahindra Sr. Software Engineer interview questions

I was gone through all the round and formalities were on the same day. I was asked to send the previous company offer letter, payslip and ID proofs. I sent everything to them. After that i didn't get any response from HR department. I followed her in the Same mail conversation.but she didn't reply. HR process is very worst

The HR from TechMahindra 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. I got my chance at 4 PM for first round.
