I applied in December 2021 for the Tech Support Engineer role in Amsterdam, and overall the process was very smooth. 1- Interview with 1 team member, questions were mostly revolved around Adyen Formula, to see how you fit. 2- Technical challenge where I had to implement their drop-in solution (they will send you a file where you can see how it works, and different solutions) and for bonus points you can style or add different payment methods which was pretty easy, they have a very good documentation, so make sure to use it during implementation. - Then 1 hour interview with 2 team members, where I was asked questions mostly about Fraud Detection, which kinda caught me off guard, because I had no experience or little knowledge about, and I was mostly prepared for other things. The overall idea was to see how you think, and they don't actually expect you to know everything.
