Pros
I am remote, however feel I sort of know the main folks at HQ. Regular communication and monthly events (yoga, cocktail classes, meet-n-greets, at a restaurant, etc). Very active engagement.
If you are living near HQ you will have more opportunities for different jobs and meetings.
Everyone at the main office is responsive and helpful when you reach out for help!!
Cons
Cons are limited, since it has only been a year. I can see how some people new to being a contractor might feel "alone" if they work remotely, but that really is every company. Understand, unless you work in HQ - your work is dictated by the contract.
