Back in the day "what happens when the user types a url in the address bar and press enter" used to be an interview question, and I remember nobody has ever mentioned the hardware and keyboard keys and interrupts. This post does! Pretty awesome detailed view of a request lifecycle.

I’ve always wanted a version of this sort of a timeline that really lets you zoom out and in to the fractal complexity of it all. Right at the end we’re talking about updating the DOM and rendering… there’s a whole Unicode and font stack and rasterization process happening in there.

I once got that question, started with the keyboard switches and the interrupts, and the interviewer sighed and asked me to get to the stuff in the browser.

I still like this question because of exactly what you mentioned. What the interviewee does and does not mention can give you a fair bit of insight into their priors.
