This can be a con for some people and pro for others: you have to be the type of person who takes initiative in their own learning and growth. There isn't really a set onboarding/training program so you have to go out of your way to get the information you need.
While the ceiling is high for education and learnings, there isn't too much room for growth career-wise. I can see this improving as the company expands and hires more employees.
