I'm sure from the outside Pinterest seems like a fun, collaborative, creative place to work, and its company size gives off the impression that it's going to have a startupy feel. After 1.5 years there I can unequivocally say that while this is the story that is advertised internally as well, in day to day life, the direct opposite is true. This was by far the most toxic work environment I have ever been a part of. A culture of passive-aggressiveness and at times complete disrespect for colleagues that are deemed "inferior" is rampant. Teams that should be working together are actively pitted against one another by management. Bullying by superiors is not only common but is basically expected as a norm. Promotions are almost never based on merit, but generally instead on whatever optics need to be pushed that month. Feedback is constantly ignored or met with empty promises that no one is ever held accountable for (or, at worst, with "if you're unhappy you can leave" or even actual firings/removals from teams if a manager finds you "difficult"). It's not a huge majority of people that are the worst offenders of this behavior, but the major issue is that the larger company seems to be content to allow them to act this way, which in turn enables lesser offenders to become worse when they see that there are no consequences. At this point, it seems like the company is propped up by revolving door of competent and ambitious people producing some good work that others end up taking credit for until they either become fed up with the toxic culture or are pushed out once they can no longer be used.
