Interesting. Incidentally, this would make a great Fermi type interview question, to replace how many gas stations or piano tuners are there in the US.

- gwern 15y agoMight be hard to estimate anything but the Facebook numbers, though. I would have a hard time estimating anything to do with the silver halide - annual consumption? Annual silver mining? etc.
- sliverstorm 15y agoI still don't understand how a Fermi question makes for a good interview question. How can you make reasonable estimates about something you know nothing about?
- invisiblefunnel 15y agoIt's likely everyone you interview knows nothing about it, so it isolates logic and reasoning skills from previous knowledge. The accuracy isn't important.
- Jun8 15y agoI don't like those type of questions either, I said it would make a good Fermi question, not a good interview question :-) For some reason, some people love to ask such questions. I'd rather ask how to perform face detection on 1 trillion images.
