The process consisted of an initial chat with a person who is on the same position as you are applying to. After that, a technical test was sent in which you need to implement a solution based on certain requirements and using Adyen platform - I chose to create a Django web app, but you can do it in any programming language (as far as I am aware) - I needed to complete this task in 2 weeks. I dropped out of the process due to personal reasons, but the following step would have been showcasing the solution. All in all, a great experience.
