I applied through college or university. The process took 2 days. I interviewed at Wipro (Velur) in Apr 2013
Interview
I had the interview for the designation of project engineer through campus recruitment. If you have an aggregate of seventy five percent throughout your career starting from high school to graduation, you do not need to appear for the written or online interview process, which is generally conducted by AMCAT within your campus. Otherwise, after qualifying the online, which includes very basic questions and tests your aptitude and reasoning ability.Go through some book for aptitude and reasoning . It will be a good practice.
After this comes the technical interview . The interviewer will ask very basic things about your stream and what have you done in technical aspect throughout college. Hr round may be the taken by the same or different interviewer which is not a big deal. It's done it you get though these processes.
Interview questions [1]
Question 1
As far as I have known, there's no such question which can be said to be difficult or unexpected. But if you want to be on the safe side, google some HR interview questions the night before interview.
