Tech Mahindra interview questions

I was invited by RMG for F2F interview at Tech Mahindra, Pune office. 1st round was taken by senior Bid manager. It was for 1 hour 10 mins. Post that I had HR round where discussion happened around salary, joining period etc. I was told that within 2 days HR will get back to candidates. It was almost 1 month back. Since then no updates have been shared, HR/RMG doesn't even bother to reply to mail or receive the call. Very poor process. I am still waiting for updates.

it was campus selection. first was aptitude which was quite simple, then 2nd was Technical round in which they asked about the our BE final project and some technical questions about java,c,c++ etc. then was the HR interview which was 3rd. All this happened in 1 day only.
