People at GitLab Say

This information was sourced from reviews originally posted on Glassdoor.

They really do live the culture and, by any large, everyone really is in it together. None of the backstabbing or ladder climbing I've seen elsewhere. Company values are an adjustment, but work out well once you decide to embrace them. It would be tough to work for another company that didn't embrace a similar ground-up approach and a similar degree of transparency.

I joined GitLab recently and I am very impressed by this organization. Processes are very clear and documented and there is always a desire to improve.
