I applied through university. The process took 1 day. I interviewed at Robert Bosch India (Thiruvananthapuram) in Nov 2013
Interview
There was an aptitude test, followed by a GD and a personal interview. It was a campus placement process. Interview was not so difficult. But they will mainly judge your overall attitude towards learning.
