They will bust your ass but train you better than anyone else. Think of it as the "high powered finance" equivlent in the oil business. Your first few years will be travel and work, nothing else.
Company culture is completely subjective based on employee status, market conditions and all kinds of other crap. Plus your kid's an engineer. That's a cyclical job market based on project flow and/or commodity prices, so he's very possibly going to be working a crapload of companies with different kind of people. Schlumberger's a big name and will probably have numerous challenging and important projects, that's literally all that matters. Jesus I wish was your kid right about now, energy jobs in the non-operational side are either cool but unstable marketing jobs, morally ambiguous legal gigs (you enjoy writing mass internal emails asking employees to call their congressman with your well drafted anti-environment talking points?) or just crappy crappy non-transferrable revenue accounting.
Heh. Necro bump. Dude is foreign or dude is a jokester. I remember this thread from way back when. I just learned how to pronounce it last december.
