Earlier quoted context omitted.
Facebook "black holed" me after two phone interviews. Had to email them them a couple weeks later to see what was up. Never seen that before. Edit: I guess "black holed" isn't the right term since I did get an interview but you know what I mean
I call it 'Ghosted'. Basically, you are talking, you both like each other and then suddenly you don't hear from the other person. I had a few companies ghost me and it was annoying. I don't entirely mind if I apply and just never hear back, I just get to laugh at them when they email me two months later asking for interview.
If someone does it to me I tend to lose some respect, but that's possibly because I'm an outsider. Maybe Californians expect that but I usually hope for the respect of a direct no. (Shrug.)
