I applied online. The process took 1 day. I interviewed at Rakuten in Mar 2015
Interview
The first interview includes an online coding test on codility.com and a pre-recorded video test (the questions are given). The online coding test was very easy. It is a good idea to do some practice questions on codility.com, in order to get acquainted with the environment.
