Very bad experience. A total of 5 stages in the hiring process, with the final stage being a talk to CEO or similar, who has the last subjective say; (never heard of anything like that, 5 stages!). The process takes months and is a complete LOSS of time. First stage consists of a 30 minutes interview with HR (generic questions, motivations etc). Second stage is gorillatest assessment (passing score 80%, takes 40 minutes to complete), 3rd stage is 2 successive interviews, 1h each, with two different analysts (30min getting to know you and 30min case-study focused on the company’s business). Regarding this 3rd stage I have some comments: the experience was REALLY BAD, they were not professional at all. The impression is that the company puts there completely inexperienced people. One of them even said some swear-words during the interview, and openly admitted on not having read my resume. I am speechless by how unprofessionally the interviews were conducted. 4th stage is a full day where you actually go to the Amsterdam office to work for a day to solve a business problem and present your solution at the end (basically working for free). And 5th stage, if you reach this, is a meeting with top management. At some point of the interview stages they will find a way to reject you. It seems all they are looking for is a reason NOT to hire you. So don't lose your time.
