Pros
They pay ontime, benefits are not the worst in the industry but has a very low coverage limit and high deductables, but fair for a contract firm. I pay the benefits premium every month, they don't contribute but maybe $50 total if at all, so who cares, get benefits from anywhere is better than their coverage for the price.
Cons
4 years ago I was very happy with APEX, in fact they were my sole recruiter I worked through. Since their merger, I have even had to talk to their corporate director about issues of non-response, bad relationships with recruiters that ONLY want to talk to you when they have an opportunity they want to talk to you about. Even when I was submitted to a position, they just went dark, no updates on progress or status, no email reply, no voicemail call backs. If I was not an immediate potential risk to them NOT making a commission that day, they don't know you! Stay clear, unless you are desperate for just any treatment. Me, a person that draws a very high rate and thus a good comission for them when I am in an engagement through them, I jumped ship, I don't need the head aches. I have been placed through another competitor and very happy. In fact, now in a full time position in a Fortune 50 company, no help from APEX!!!
