I applied through a recruiter. I interviewed at Rakuten (Tokyo) in Mar 2021
Interview
zoom interview is the first then coding test and another interview. Overall it is average and focuses on the experiences and ideas instead of practical techs. Coding test is average as well but will depends on the position you apply. Two tasks, one is for data processing and another is the statistical modeling.
