Pros
Okta is doing great things. They have very smart people on staff and are mostly friendly. Benefits are good as well. If you got in early, stock options are quite valuable.
Cons
The team that I was on was severely understaffed (less than half of what was needed). It was not uncommon to work extremely long hours to get things done, even with other projects and tasks slipping because there was simply not enough bandwidth. There was an open headcount, but one person on the team was moved to another team and the headcount was suspended due to budget issues. Remote employees are often treated as second class. There were numerous times I was on a scheduled meeting but the organizer never dialed in. Equity regrants were minuscule compared to initial offer.
