You have a talk with a recruiter followed by initial interview with a senior data scientist. If you make it past the initial interview you get a take-home task followed by a final round of interviews (2 case studies and a behavioral interview). The talk with the recruiter and initial interview with senior member of the data science team was fine. Recruiter sold the company well and outlined the process clearly. My main issue was with the take home task. You are given a dummy dataset along with a list of questions. First half of the task is theoretical while the second half is empirical. The format is fine but it’s the amount of work you have to put in at this stage in the process was excessive. No clear instruction was given on how long it was supposed to take. All in all I spent about 5 full working days on the task. Other big players in industry provide compensation for the take home part of the interview too. My advice once you get to the take home task is to spend no more than 2 days of it (long weekend thing). In the end, you aren’t being compensated so your labor isn’t worth anything to them at this point.
