This place has a very unsettling vibe. Everybody who interviewed me kept saying what an amazing place it was to work, but there were two major gaffes in the process that made me think otherwise. First was that I was scheduled to be there for two hours and ended up there for five, over lunchtime. While every person I spoke to talked about the amazing free lunches there, and my interview was right next to the lunch area, nobody offered me anything to eat, even though I was there far longer than expected. I only managed to make it through the day because I'd happened to pack my own granola bars! (They did offer water and coffee, which is all I'd normally expect in an interview, but for a place that touted all of the supposedly amazing ancillary benefits were, like delicious free lunch, it was really strange.) In those five hours, there was a LOT of dead time waiting for the next person to show up (and listening to the crowds eating their lunch as my stomach grumbled).
The other gaffe was when the HR coordinator CC'd me on a group email soliciting feedback for another person interviewing for the same job as me with a lot of revealing information on that candidate. Anybody can make that kind of error, but it was the sort of thing an HR person should be used to being extremely careful about.
The interview went OK. The hiring manager was pretty arrogant, though, and I didn't have a sense I'd particularly like working for him or for the company in general, so I wasn't hugely disappointed when they didn't call me back. I also have never at all been sold on the company's mission or its value as a consumer product/site.
