Be prepared to put your personal life on the back burner.
Pros: Big paychecks due to immense overtime hours
Cons: Never know when you will be home, schedule is always changing, you are not taken seriously by management.
When I initially interviewed for the position I was excited. I was told every 6 months I would get a pay raise and within 2-3 years I would be promoted. I worked for nearly a year before I got fed up with the office politics and left.
In the 11 months I received one small raise (less than 40 cents). I worked myself to the bone (55-70 hours/week). Schedule changed everyday. You never knew what you would be done, an 8 hour day turned into 12+ because the project managers didn't take the time to properly setup a job. All responsibility falls back in the Field Techs. They want to hire college grads but want to pay you like high school grads (15/hour). May work an 8 hour job and then come back to the yard and unload trailers of supplies or drums or clean garbage up in the truck yard.
They tell you in the interview that you will not work that many Saturdays, but between April and October you will be lucky to have off one Saturday a month, working 6 days/week.
The "training" program is trash, you will be more confused after going to the program than learning on the job.
You are required to expense all hotel, supply, truck breakdowns on your personal credit card (4-6 week payback period).
