Pros
Great pay for a civil engineer that can't be beat working for traditional civil engineering companies. Good work/life balance (most people get into the office by around 8am, and the parking garage is cleared out by 5pm). Good flexibility in working remotely if needed for doctor appointments, etc. Great networking opportunities within the company and you can have fun playing the corporate "game." You get a new position every 2-3 years so never get pigeon holed into doing only 1 thing.
Cons
Everybody in my group quit (a trend these days), so my hours have been closer to 12+ hr days. Honestly I'm just not passionate about oil and gas. The pay can't be beat if you're a civil engineer, which is why I decided to give the job a chance. I'm actively looking for jobs elsewhere now because I can't scratch the itch for wanting to work on a civil infrastructure or building construction project (the reason I chose to get my degree in civil engineering).
