What people at Auth0 say
Reviews originally posted on Glassdoor.
People are incredibly passionate about the company. Peers are always willing to help, no BS attitude. Lots of smart folks, constant learning opportunities.
Fantastic culture. And I mean it. It goes way beyond published "company values" (which I'm always skeptical about anyway). This particular group of people truly give a sh*t about what they do, how they do it, both at work and in life.
You can work remote full time (depending on your role) and the company is fully invested in making sure you are happy and successful.
Despite we’ve growing so fast the culture of Learning transparency and team work has been always present.
Remote work, no fixed schedule. You are trusted to do your job, because the people that get in are good at it and like it
