Well, that screed I wrote, is a fairly typical "geeky conversation" that can be invaluable, in an interview.
I used to hire pretty senior-level engineers. They would be writing C++ image processing pipeline code, to some insanely exacting standards.
My technique was usually to get them relaxed and comfortable, then start asking them for stories about the projects they've worked on. It was always a joy, when I could get them to start chattering, like the post above. I would look at the enthusiasm, and the passion, as much as the technical detail. I'd love hearing them talk about discovering problems, and how they addressed them.
