I freeze under pressure, too, but I work in an open office and have no issue with that. It's not reasonable to literally watch over someone's shoulder while they're working. That's just interview hazing. They do it because the people who hired them did it, on down to the first engineering employee hired by FB who probably had it done to him/her because the people interviewing had no idea how to interview any better.

BTW, what's a "fringe list"? Googling that term shows me results pertaining to the TV show Fringe (which is great, but I'm sure not what you're getting at).

I guess it's not broadly used terminology but it was common when I was at uni: http://mnemstudio.org/path-finding-a-star.htm - It's basically a list which you use to hold nodes which you haven't visited yet and you expand them in-place and pop them off as you visit them.

Oh, right, like the "seen but not visited" set you maintain when doing BFS.
