what moneyshot said! dont ever pay any of them the ones with actual openings get paid by the company to find the right people. I've worked contract for a couple of different companys now all you need to do is send in your resume and start talking to them and see what they may have open. I would prefer a real full time job with company so I can accrue vacation and benefits but in this economy ya take what ya can. so here's who I've worked for most are the same but money offer and benefits may differ:
Aerotek-twice,cad designer, big company good rep. nationwide.
Epcom in troy, small, one main account, design engineer @ General Dynamics
d. Diversified Tech in Southfiled doing a week-to-week gig with Molex Auto in Auburn hills.
currently design engineer thru STI in Novi placed @ unisys in plymouth.
also try:
RDS, Inc.
future tech
modern engineering
MSX, intl
basically look on MONSTER.com in the detroit area and you see any that have openings.
Here the best way to talk to most of them in metro detroit, go to a job fair there's always one in Troy somewhere. the job fairs are usually 90% headhunters 10% actual companys HR people. Wear your interview clothes or at least business casual and bring lots of resumes and a copy on disk they can download. I've a business card stack two inches high from all the recruiters in metro detroit. Almost all recruiters do hiring for all types of white collar and blue collar work so in detroit you get lots that actaully specialize in automotive this includes all engineering types, accounting marketing, reception, you get the idea.
My opinion they are all middle men and are encroaching on my ability to make more money in my field. The idea of these companies is that they have the network to talk to the HR people at the company with the opening and that company goes to them looking to save time and money by hiring people on contract that they can get easily rid of when the project is done after 6-months to a year or whatever. damm bloodsuckers. but oh well what are ya gonna do.....do I sound bitter? <_<
