1st round was perhaps screening round and included general introduction, getting to know project management, implementation experience, interest in payment industry and cultural fit based on Adyen formula.
2nd Round was a technical or presentation round where I was asked to explain the Adyen drop-in solution to a client. Panel included two Adyen senior implementation managers.
I was given a developers assignment instead of implementation assignment and there was a lot of confusion as to what are their exact requirements and to what level are the technical skills requirements.
