Pros

Good pay. Good options. Good location. Some good people on the team that you will befriend (that will eventually be let go).

Cons

Terrible management -- verbal abuse -- firing if you didn't fit into the boy's club or speak up about anything you don't like or refuse to do. Brogrammers. Management mislead people after layoffs so no one bought their options. Now Slack is valued at $2B.
