Amazing work, above average pay scales, if you are a problem-solver - this is where you will love putting your skills to work. By virtue of being "independent" or "foreign", the company gets some of the creamiest corruption and crisis related work that any nerd could find. You will get good opportunities to work beyond your job description if you can make a case for it. The structure of the company, although large, is relatively flat and flexibly - which means if you have a good idea, implementation is neither slow nor hindered by red tape. Being a company that comes out of war - supports war - profits from war - and that traditionally hired former government employees / ex-spooks / coppas - every one is super happy to be out of government regulations and into self-regulated speeds of how work or information can flow.

Hopeless HR, Poor mentoring, White-Run, Colonial - The first two being important for young consultants. It will be true that you will be treated like a cog in the wheel, replaceable at a moments' notice - but then that is how fast companies work. Mentoring opportunities are thrown around as "bait", a massive pool of intellectually strong employees continue to pass through CRG offices the world over - so the idea that this company has massive turn over is spot on. The HR tries hard, but there just is not enough support for employees - who work on some of the most sensitive confidential information.
