Personally, when I see FB on a resume, it’s a factor. I want people who will help push the company in a healthy direction. There’s always pressure to make changes to the app that increase addictiveness without adding actual value to the client, and I’m proud to work somewhere where colleagues push back on that kind of thing. Working at FB is a (relatively weak) signal that they won’t be that kind of colleague. It will come up in the interview.

If they can convince me that they stayed there in a ‘change it from within’ capacity, great. Otherwise, yeah it’s a negative signal.
