Pros
Okta is solving a hard problem. There are many other companies in this space that are not as big and as successful as Okta. So its fun to work on that problem and helping define the market. Everyone is smart, helpful, has a great growth culture/mindset. If you are early/late in your career, you will learn a lot and add a great bit to your resume. The co-founders (Todd and Freddy) are incredible and genuine leaders. They are a great manifestation of "lead by example."
Cons
Depending on the department, it can be pretty top heavy with a ton of management hierarchy. This really does suck. I think there are intentions to be transparent but it's poorly handled. There are also many people managers who are first-time managers because of how fast Okta grew - they are also learning this as they go and sometimes it doesn't work out too well.
