I applied online. The process took 2 weeks. I interviewed at Adyen (Amsterdam) in Dec 2019
Interview
The process was to a vacancy in Amsterdam.
It consists in two online interviews, one test, then a full day of interviews in their place.
It was a bit confusing since the people interviewing wasn't from HR and they didn't know how to properly conduct it.
Interview questions [1]
Question 1
Especially in the second interview, people asked for some things that only makes sense in their heads, so it was difficult to understand the question and, when it did make sense, it was stupid.
