I've interviewed for the Senior Data Scientist position in May/June 2018. I've gone through four rounds of interviews (Phone screen with HR, test assignment, skype with People Manager, skype with 2 Data Scientists). Everyone i've interacted with was extremely nice, knowledgeable and professional and the interviews have gone well - I've recieved positive feedback after every round including the last one, after which I was told that they had to finalize some details and that I'd get an update next week. 10 days later i had to e-mail them for an update and was told that they were currently "fully staffed for Data Scientist positions" which is a genuinly upsetting thing to hear after you've wasted a month of your time preparing and interviewing

The process involved a telephone interview with the HR responsible, an offline exercise to be done within a few days, a personal interview with the people manager and a technical interview with the team.
