Rakuten Software Engineer interview questions

Applied through my friend. Got invitation to an online coding task and long form to fill my details. The task was limited by 1 hour, but I was able to choose any time to start, within a week. So I had plenty of time to prepare. After solving the task, got rejection with polite appreciation of my skills, with no direct comments on task solution. The process was quite clear and streamlined.

I applied this position from college. There was one online codility test at first containing 2 questions and then an onsite interview coming in 2 weeks about 30-90mins. Mine was whiteboard interview for the onsite.
