Vantaggi
The people you work with in a similar role (junior scientists/engineers, geologists, etc.) are the only thing that makes the job worth waking up for. The office environment, if you ever spend time in it, is an open concept floor plan.
Svantaggi
While at ERM, I have seen more people leave the company then were promoted. Promotions are few and far between, when they happen, there is not much in terms of a pay raise or job duties. You get a new title but you still do the same work. There is a heavy amount of "project managers," if this is the direction you see your career, do not consider working here since you will not get experience in this until who knows when. Rather, you will be a field tool/data collector/technician to gather data for these project managers, often working over your salaried amount of 40 hours, with no overtime since it is considered an exempt position. Consider adding on $5-$7k to your salary before accepting. When in the field, the job tasks are very mind numbing and boring. Interns or field technicians paid hourly should be doing these tasks, not someone with a college or graduate level degree.
