Marqeta Software Engineer interview questions

I have a conflicting feelings about the interview process. It was simple overall + unreasonable system design that they call FE Architecture/Design. It actually was system design that required a lot of security knowledge and prior understanding why the company needs that system. Instead of giving a design question where every engineer might have some level understanding and can express it, they decided to discuss a system that engineers of Marqeta built for that company, but most engineers won't have an experience of even using it.
