It were 3 months of interviews and tests. First I spoke with HR assistant. After a week, I made a video call with the UX/UI design lead there, a very nice guy. Then I went to Adyen for a personal interview. After 2 weeks, talked again with Tim (UX/UI). I managed to pass on a design test. Then the chief of HR department interviewed me. Very lovely person, although lacks psychological background wisdom to understand basic things. After that I received an email saying that I wasn't the perfect candidate for the position.
