I once interviewed at Microsoft. The hiring manager asked me how I would go about programming a break point if I were writing a debugger. I started to explain how I would have to swap out an instruction to put an INT 3 in the code and then replace it when the breakpoint would hit.

He stopped me an said he was just looking to see if I knew what an INT 3 was. He said few engineers he interviewed had any idea.
