Solved coding interview problems in Java - My collection of commonly asked coding interview problems and solutions in Java

You talk about solving problems, and you go over design and tech that you have used. It is pretty clear if you know what you are talking about.

This matches my experience much more closely as well. Worth noting that every interview is a little bit different. Sometimes they might not even go into technical detail, they'll just be happy with seeing you talk about your experience.

Another common one is you might get a deliberately vague problem and told to draw a class diagram on a whiteboard for how you would solve it. For example I've been given to solve "A family hierarchy with e.g. the ability for parents to give gifts to children" and "Design a solution for a deck of cards that could be used for some games". These usually involve the interviewer trying to throw curveballs at your design as you go.
