You are probably looking at this page because you want to move on from your current job and a recruiter from a company you've never heard of called you with a management consulting job making way more money than you do now even though you have little or no consulting experience. It is indeed too good to be true.
You will talk to a very nice recruiter who will get back to you promptly. How often does that happen?? You will talk to a very nice man who reminds you of family. He probably won't be able to remember anything you talked about over the phone when you meet him in person because, while his objective is to make you feel special and "chosen" he is interviewing anyone who can breathe because they are running through people like you everyday. When a company of this size lets you know every week that 1-4 people have left - that isn't just because of the travel as they would have you believe.
You will be told a story of how wonderful the company is and how they want to grow their employees the DB&A way. Maybe others have had this experience, but just remember that the people out in the field have a differing agenda from all the others you will have contact with during the recruiting and orientation process. I'm not sure if this is a case of the old guard running a passive/aggressive fight against the new, but something isn't right.
Everyone gets graded out at the end of every project. Your grade is based on your individual performance as well as the overall project. This is what the Project Manager's bonus is based off of. Same situation for his boss, as well as your possible promotion. That means that if you are new, and placed on a project on a tight budget, you may not make it very long. Your manager and peers have a vested interest in seeing you fail because you are a cost to the project. Your airfare, hotel, etc are all charged to the project which is the majority of the project cost. If this is a project with a 9 person budget and you, as an on-boarder are dropped in their laps as #10....good luck. The disgusting nature of this is something you should not overlook.
The only person out in the field you will talk to during recruitment is a Project Manager, Listen carefully. If something sounds off, trust your instincts. This person could wind up being your first boss.
Look, if you think you can survive as the new person in a kill or be killed workplace, give it a try. Just remember that you might get put on a project with team members and managers who take no prisoners (there's a good deal of money at stake) and are not necessarily as friendly or helpful as the people you encountered previously. Either the home office is blissfully unaware of this, or they don't care. I'm not sure which is worse.
None of this review even includes the brutal travel schedule or possible terrible project environments you'll deal with. Keep that in mind. Before you accept the offer from DB&A (don't worry, you'll get one), think long and hard about it because to call this a risky career move is an understatement.
