I applied through a recruiter. The process took 1 day. I interviewed at Rakuten (New Delhi) in Aug 2019
Interview
Went for Interview in rakuten office, first round data science mcq test with 30 questions. Next round after 2hrs of waiting with Japanese guy on WebEx .He didn't ask any questions ,just ask to explain what you are working on, which framework, library do you use . Then waited for 1:30 hrs, went to hr for further details,she told that you rejected as you are weak in statistics, ,then I ask he didn't ask single questions,how he had come to that conclusion. she said your profile not fit for job this much experience, I ask why you had shortlisted me , then she said we didn't done that ,it was through consultancy. Total waste of time.
