I applied through university. The process took 1 day. I interviewed at Rakuten (Bengaluru) in Mar 2012
Interview
they ask regarding your interests in the engineering subjects. and test your overall intelligence not specific to the job. lateral thinking abilities and creative quotient. very simple but can be challenging depending on your mindset . if u r confident and relaxed things can turn out favorable to you.
There were two technical rounds
Questions were mainly on Java, Automation and some manual testing questions were also asked . The interview process was very good. It was overall a good experience.
