Not surprising that the recent positive reviews are from recruiters. The product and the company's culture are surprisingly opposite.
While the product is progressive and cutting edge, the culture inside feels like a 1980's corporation. There are definite examples of nepotism and the executive team is all male and all white with one exception. So are the new 2nd in line leaders those executives have put into place.
Career paths don't exist so progression is pretty rogue and definitely political. There are several examples of very talented and motivated folks leaving the company for this reason.
What to expect day to day: There isn't that fun chatter and friendliness that you expect from a typical start up in the bay area. It's pretty stodgy and awkward and there are odd tensions within and between teams. Worklife balance is supposedly important but the leadership doesn't act like they really care about it or embody it. It's hard to understand what the company truly cares about beyond growing revenue. Surprisingly, there is no obvious culture for a very mission driven product.
The company hasn't had to compete yet with the big dogs in silicon valley like Google, Facebook, LinkedIn on culture for talent, so it's focusing on growing its wallet. Culture and politics are Impossible's Achilles' heel so I can see why people go somewhere else.
Think carefully before coming here!
