I didn't have anything to compare it to at the time, but no cons really, you just have to be in to the work if you're going to motivate yourself to move up.
No benefits for my specific contract other than 401k and ok insurance for healthcare, Contractor Care team rarely reaches out to me to ensure im doing ok and have no issues. In the last 10 months i've heard from my apex rep 1 once and that was to notify me that a new rep was taking over and they never reached out.
