Domande di colloquio per Graduate Java Software Engineer presso Adyen

The process is ok but very long. From what I know, if I am able to get an offer, I need to go through 7 round: 1. HR (culture fit, why Adyen, why move to Netherland) 2. Two engineers (why Adyen, tell me a project you are most proud of) 3. Codility test (easy level) 4. Interview with two engineers to discuss the codility test (prepare for the details of the codility test, why you did that in that way, what can be improved (time complexity and space complexity), why Adyen. I failed here. Reasons are unknown) 5. Interview with the technical manager (I did not proceed to this round) 6. Interview with prospective colleagues (I did not proceed to this round) 7. Interview with one member in manager boards (I did not proceed to this round) In general, I do not have too many complaints about the process. It is just that I got rejected for unclear reasons and ask for feedback but never got reply.
