A job-hunter wrote me that he wanted to change fields and asked if recruiters could help.
My experience is that recruiters work best placing a person in exactly the same sort of job he/she has done before. It is extremely difficult to change industries and/or functions with a recruiter. If you have strong functional credentials, e.g. a CPA, you might be able to change industries for example from a for-profit to a not-for-profit. But if you really want a career direction change, getting introductions and leads from people you know well is the most effective path
