I applied online. The process took 2 weeks. I interviewed at Adyen (Amsterdam) in Sept 2021
Interview
The first interview was in the form of an introductory interview with two java engineers.
Hackerrank test as a second step with 4 questions. Data structure, sql, uml, review questions.
The third interview was done as a review of the hackerrank test.
Although I did not do well in hackerrank, they sent a meeting for the review, they said that they would not continue even though the review went well.

I applied through an employee referral. I interviewed at Adyen (Amsterdam) in Feb 2021
Interview
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.
