Tech Mahindra interview questions

Walk in interview, extremely easy. got over in almost 4 hrs. When I walked in they asked me fill some forms regarding my information and my old jobs gets, Asked me produce my last companies offer letter and leaving certicates etc. Once all that was done, I was sent to a room with two people in it. They asked me questions related to my skills. one that stage was cleared I was told to do a telephonic Interview with one of the senior person. Once that stage was cleared last stage was HR Round and Bingo next thing is you have an offer letter in Hand.
