1000 perfect does . I worked as a recruiter for a number of years at certain Job fairs, and have had several several friends all get picked up from Job fairs . Plenty of people have gotten picked up without them sure , but I can promise if you aren't getting the call yet , it can't hurt.
They def help, understandably they suck , you gotta spend the money , the time, the suite etc. but if it gets you that call it would have been 1000 times worth it .
