Pros
After working for two Fortune 500 Companies (38 and 68), I've never been happier working for Paycom. The people that work at Paycom are BOUGHT IN to the vision and purpose of the company. Paycom does a fantastic job taking care of it's employees (e.g. beautiful and clean campus, nice break rooms with coffee/water/ice machines, $4 onsite lunches, Employee Appreciation days, etc.). My FAVORITE thing about Paycom is the opportunity for growth and the ability to make an impact...regardless of your title or level. I was apprehensive moving to a "smaller" company after working for two Fortune 500 companies and boy was I blown away. My only regret would be not going to Paycom sooner (had I known about it).
Cons
I wish there were more opportunities outside of the Corporate Headquarters location in OKC.
