    Not sure what to answer.

    I think it is not about what is high speed or not ... it is more like, some boards may work even if the layout is not perfect. When I am designing boards I always keep in mind "high speed" design rules and recommendations and try to follow them. And it doesn't matter what kind of board I am designing.

    But maybe to be a little bit more specific I started seeing recommendation for "high speed" design for boards with memories from 300MHz and up. Today, when you are designing a CPU board with DDR3 memory, it will probably have USB, LVDS, maybe even PCIE ... all these should follow the high speed rules.

    I am not really sure what they can ask on interviews. But, if you like, have a look at some of my latest videos, we speak there about how signals are travelling on the boards and that can give you some ideas what it is about. For example, you can start here: What Every PCB Designer Should Know - Return Current Path (with Eric Bogatin) https://youtu.be/icRzEZF3eZo

    Hope this helps
