Expect the pay to be below market value and no support when it comes to you achieving the career goals set forth yearly for your review. They are always advertising positions on their internal job board but, when you apply there is either no real job (just getting resumes) or you get one only for it to be taken away. You will be told it is a financial decision and you need to stay on the current contract. In other words, you are just a paycheck to them. Meeting with your CM or Sr. Associate about needing a change are met with "We'll see what we can do." Once again, there is no real intent to move you to somewhere where you and the firm can both benefit from your expertise. Instead, they attempt to temporarily appease you with award money and promises that they are "looking to move you over soon."
Also, for a "consulting" company, this is one of the most technology behind companies I have ever worked for. They cannot figure out how to digitally sign documents. Everything is print, sign, scan, and then email (or snail mail). I worked in a company that was 1/2 the size and they could digitally sign documents.
Finally, they will want you to pursue certifications that they want you to have even though you do not want them or interested in getting them. The idea is for them to market the certifications on proposals. Once again, they do not care about the individual; only what makes the firm look good on proposals and contracts.
