I filled in a form, sent my CV, and they selected me for a process. After developing what they asked, all I got was a compliment on the strengths of my codebase, but they gave me a very vague feedback saying ti didn't cover all the scenarios which is false, as they didn't even bother to review it properly. They even went as far as telling me that my code was too complex which I completely disagree with, there is nothing complex about it, I followed OOP principles, and it was very readable, I wrote 20+ feature tests, terrible feedback. I don't regret participating in the process, but I hope my review helps someone who might participate in the future.
