Fluor is overall a decent place to work. The people are great, the work is interesting, always something to learn, competitive pay, and there are lots of opportunities to work abroad (or so it seemed). Your experience may vary on the projects you work on, and your manager. Overall a good experience.
If you are a new grad, and there is no project work, you may be very expendable. EPCMs need backlog. No backlog and no projects means limited overhead and very little job security. If you have more experience and you have a niche for yourself, you will be fine.
lots of opportunites, good people and decent pay
job security in epcm's can suck when there is no backlog
