Tech Mahindra Associate Developer interview questions

First round was online aptitude test, if you qualify that you get picture composition. After that I had PI and HR interview.As was from Mechanical Department I had to face a separate panel where the person asked me only mechanical related questions and mostly about my academic projects. Then after that I was sent to the HR and he asked me why I chose Tech Mahindra and why I did mechanical engineering. Then he asked for my Cv and photocopy of all my documents and then announced that I (along with many others) was selected.
