Obviously the way this goes down is different for each interviewee and each interviewer.

I personally remember a lot of details from some of my favourite projects, but I wouldn't hesitate to say "let me grab my laptop and I'll show you" because it will be clearer. Then I'd walk the interviewer though all the details of the code, deployment, testing, etc. etc. etc.

Yeah valid points, some companies do that, but I don't think that scales to every candidate who doesn't have a project that isn't protected IP.
