I've worked in the software industry for about a decade now, but I have a penchant for being extremely terse. So in interviews when asked questions with a specific answer I do fine, but when there really isn't any concise answer I tend to lose the plot a little bit.
Just as an example I get asked "whats the difference between C# and c++" all the time. I could talk about the differences all day or I could just say "Well X is y and A is b" and it would take like 10 seconds but wouldn't be complete and doesnt demonstrate my knowledge at all.
Should I start with what an electron is and how transistors work then continue into how we leverage those to create a "binary" protocol which can be used to blah blah blah computers yada yada operating system blah blah blah typing et cetera et cetera
I guess what I'm asking is how much is enough? I don't really care about their time as I tend to be very annoyed by this type of question, but I'd rather not waste mine.
