If you're an engineer I'm assuming you can usually fight your way through a problem they give you. A lot of places I interviewed seemed to do the same thing -> (man I have an interview, better google a few questions to ask them).
The important part is that you look at their job description, you will usually cover 75% of the interview preparing like that.
The moment a company enters growth phase and they need a lot of talent, nearly everything goes out of the window. Most (not all) job descriptions become generic and less thoughtful and they resort to generic technical questions in interviews, simply because there aren't that many candidates who have relevant backgrounds (e.g. I need someone to work on deployment systems, but you have payment systems background) and they can't wait forever.
Obviously there are exceptions on both sides, but this is generally how it pans out, in my experience.
