I applied online. The process took 1 day. I interviewed at Rittal (Bengaluru) in June 2017
Interview
1.Aptitude Test
2.Technical Round
3.HR round
Aptitude test was mixture of numerical,reasoning and General science.
Questions in technical round was mostly from the specialization and from resume as well. But interviewer made everything comfortable.
HR interview was pretty robust.You should justify why you should be hired and you should justify your career objective according to the course has been pursued.
