Interview process is lengthy and can take months. First they have an informal round, which checks your interests and understanding of Adyen at high level. Its outcome depends on your motivation and your skill to explain it to the interviewer clearly if you are aligned to the culture it carries. Then comes the harder part of technical case study. In fact, it is not hard but you are at interviewers' mercy. During preparation of test case study, you are informed and expected to know high level understanding of a particular product Adyen has developed. However, during discussion they expect you to know everything. They ask questions as if you have been there for 5 years already and they expect you be at the level they sound like (even when you tell them you have not worked in this industry before). If they like, they can break your flow of presentation by saying "that's it" and you wonder how about even appreciating efforts you have put in the presentation and understanding their product. So, overall it looks like a gamble game, if you get a genuine interview panel who gives you time and understands your potential, you may survive. Else, they have already assumed you know nothing in all years you have worked (as you are not able to answer technical depth of their product) Post discussion, you wait feedback and don't hear until a follow up is made. So, if you get such interview panel, then best of luck!
