I applied through a staffing agency. I interviewed at Rakuten
Interview
I generally dont do this but I had a very bad experience , people can ask you to turn on camera but no body in a panel of 4 would have curtsey to turn on their cam. They wont tell you what is the role all about or how they do analytics . Manager will tell Hr would tell you which they will never. Also have you seen people showing off there data science skills , if no please go ahead and attend the interview. If you know , what they know it is good ,if you dont then you selected .
Also please give exact answer in technical terms to a language specific. Like in python random forest has n_estimators as parameters not no of variables.
