Isn't this a bit of revisionist thinking? I don't know that cameras of that quality were commonplace in 2006. It's not like you could just pull out your iPhone. And most digital cameras weren't much better (i.e. I wouldn't trust being able to read handwriting from their pictures). So then what, you supply each interviewer with a roll of film and a company darkroom?

It's also easier to write your own notes down this way too.

2006 was... early. I don't remember when HCs were formed, but there's no way the internal ATS had any level of sophistication, if it even existed then.

(Admittedly this is all years before my time.)

From what the recruiter told me, there was a hiring committee but their recommendations had to be approved by the founders before an offer could go out.
