    Interview

    I applied online for the Data Science postion in San Jose in March 2020 and a recruiter reached out within a month. I had 3 rounds of interviews. First 2 rounds were 1 hour telephonic call with hiring manager and product manager, followed by a take home assignment. The second interview with project manager was supposed to be a technical interview but due to technical issues and long discussions I had to take the take home test. This was supposed to be followed by a panel interview.

    Interview

    The impression I got after 5 rounds of interviews is that they're very disorganized, employees do things because they're told to not because they know why. Very unprofessional interview process throughout.
