Rakuten Software Developer interview questions

My experience of first interview of rakuten mobile, I submitted open ES file and got interview notification in the end of May. The interview is processed through Skype and takes 10 mins, all questions are in Japanese.

1. Online coding-test 2. Offline interview Coding-test is super easy. Only one problem is given and it's level is about college 1-2 grade. Interview is also easy, but you should tell interviewer to strong motivation of application. I compared Rakuten with other IT companies, but they seemed not convinced.
