Pros
There are some things that make Seer a remarkable place to work. Lots of really people-centric perks and an atmosphere that, I believe, genuinely *tries* to treat people well. Management takes employee surveys very seriously. Also, some of the nicest people I've worked with. Company culture encourages forming community with lots of online (and fun) chances to interact with coworkers.
Cons
One of the biggest problems is a personality monoculture; pretty much everyone there falls into a similar working style, so some of the accolades start to seem a bit like a popularity contest after a while. Also, because people are so nice, I think that there are several hard conversations that simply aren't happening. As a result, communications gets a little jumbled and initiatives get rolled out with insufficient forethought.
