I applied as a java developer (graduate program). There were 5-6 rounds which consumed a lot of time (If you pass one round, then you'll be moved forward). HR screen > introductory session with one senior dev (introduce yourself, why you're interested in Adyen) > Hackkerank > Code review with one tech lead and one senior > so on.. I failed at code review, they asked a lot of deep question to determine whether you really understand java.

I have been setup with first interview with a recruitment person. He has asked only a very few questions such as why are you changing the job. After that I got rejection email. I could not understand on what basis are they filter a software developer after a brief chat.
