I applied through university. The process took 1 day. I interviewed at L&T Ramboll (Chennai)
Interview
Interview process contains three rounds. They are
1. Numerical aptitude
2.Technical aptitude
3.HR and Technical Interview
It will be easy until you get into Interview. After that you will get unexpected questions. But it will be surely helpful for you in future to progress.
Then be sure about your basics and go. Get ready for every answer reasoning.
