Velocity Software Solutions Associate Software Engineer interview questions

Took an MCQ test. Passed that. Called for offline interview , but except interview , everything happened. Another MCQ , 7 of 25 students selected , including me ofcourse. Next round was for coding , on pen and paper. This was very bad according to me. Then they asked to do on pc as well. The process took more than 8 hours. Only 2 selected I don't know how.

First round was a online test based on aptitude,reasoning , mathematics,SQL & C language questions. Second round was technical coding interview process.I have to do 5 coding programs and 2 complex sql queries and essay writing on e-commerce growth. I have solved all the problems. In 2 programs I done small mistakes that was like typing mistakes. But they did not hire me.
