Pros
-great opportunities for advancement
-great benefits (401k match dollar for dollar up to 5%, plus they give you another 4% on top of that. medical, dental, vision, all there. and GREAT for expecting parents, especially mother's. the leave of absence for having a child even extends to adoption!)
-great atmosphere around other great people who all work hard towards a common goal.
-the location is convenient and awesome. we have a carwash company that will wash your car while you work, 2 cafes and starbucks, a gym, a parking garage, great security, and a walking path that wraps around the facility.
-they have a great educational reimbursement program so that you can go to school and work (as long as you are pursuing something that benefits the company, obviously)
-you will start with 15 days of paid vacation, and gain more as you work for the company longer. also, you can roll over 10 days in to the next year if you don't use them.
Cons
-it's part of the oil and gas industry, so there is always an imminent threat of layoffs
-sometimes there is room for process improvement when it involves pay, as far as how and when you'll be eligible for a raise (for some positions, mine included)
