This guys is fishing for info. Won't give any details of what he does and his company name makes you think he's the real Mitchell Group (i.e. without the 1 at the end).

I came across your resume and was impressed. While I don't work in your area,
some colleagues of mine do. They may be able to assist you with your job search. They are part
of my agency network who work exclusively on behalf of qualified management and executive
level professionals.
Would it be alright if I forwarded your information and suggest they call you?
If so, simply reply to [email protected] with attached resume. Please let me know.

Sincerely,

John Mitchell, VP,
Mitchell Group
