Pros
If you suck up and bust your but you can actually learn a lot. Unfortunately you learn from yourself as those around you are likely your own age and inexperienced. You need to make the most of it and be very optimistic because the pessimists don't last here- they (are forced to) exit quickly.
Cons
They will tell you that they love being challenged, but they don't. ALL decisions come from the CEO. Every single big decision comes from him. Tech, sales, editorial, it's all in his hands and that's unfortunate for anyone in a leadership position- your opinion is worthless to him. He will be the demise of this organization and every employee that works closely with him has left or will be conned into staying- through false promises of achieving their 'vision', through equity or through straight up bullying. He doesn't try to hide it. He's a terrific salesman but a sociopathic CEO. The culture is writing on a piece of paper, it's worthless. Allegedly it was once good, now it's negative, sad, and gossipy. The only cultural influences around me are the original team members who joined the company years ago, they seem to be the only people here who care to negate gossip and prohibit the negative atmosphere, but they also look defeated and tired and over it. The new space is gorgeous but everyone can see what is going on around us.
