Don't waste your time on the assignment. Adyen sent me a development assignment with a detailed list of requirements and expectations, going so far as to provide images of expected UI design.
At one point, I emailed the company to clarify their expectations, and they told me to implement it however I think best. I built the app to tick off all their provided requirements and wrote extensive documentation for the decisions I made.
After one day, I received an email telling me I failed the assignment, and that they'd send feedback shortly. Two weeks later, after lots of nagging, I finally received the feedback. It told me I failed for a number of bizarre reasons, including:
Overall, it feels like they spend a few minutes grading each assignment. It's clear they don't bother running the app or reading documentation – they just skim the codebase and reject based on gut feeling.
A total waste of time and very disrespectful from Adyen. On the plus side, I submitted the same assignment to a different company who loved it! So thanks, I guess!
