There weren’t any unexpected questions / big surprises. It was not an easy interview process. It was challenging but pleasant. One or two questions took me to / beyond my technical comfort zone. I think the process is designed to take someone to their technical limit.

I don't think the majority middle-level management understands their business and their employees even though they are with their inflated titles...I don't think they can retain the real talents in the company for technical person since they actually don't need. They claim they are doing some high-tech stuff actually they are not and they don't understand, and they don't want to understand... They actually don't care about tech stuff, the way of doing business in their company is super easy and you only need to do better at sales, design and guide the product as not a high-interest consumer loan.
