Pros
GitLab offers an 'environment' in which all team members are enabled to succeed - from ensuring correctly spec'd equipment is made available (globally) to their unique and thorough onboarding mechanisms and the role specific training - every touch point has been carefully considered making sure everyone can not only quickly immerse and begin to contribute but do their best work while doing so. GitLab walks the walk making sure that the company values are breathed into every facet of the business i.e. collaboration + results + efficiency + diversity (and inclusion) + iteration + transparency.
Cons
At first some of the tech-speak may seem intimidating to new team members - this is quickly overcome through the training mechanisms and handbook however it can be overwhelming (particularly as someone who had never used Git prior to joining). It can take time to establish a rhythm / routine if this is your first all-remote role - you may find yourself online for longer than anticipated for the first few weeks.
