Pros
This is the kind of company that provides great growth opportunities and encourages you to do so in every possible way. They will gladly pay for you most of the amount for courses / conferences / certifications. After all, when you grow, the company grows with you. Also, any of your initiatives will be considered, and most likely will receive the green light for implementation.
Cons
This is a very subjective thing, everyone can find disadvantages for themselves. Everything suits me completely.
