They'll randomly contact you about positions, ask for all of this personal information and "right to represent you," claim to forward your resume and then you'll never hear from them in regards to your "application." Companies like this just try to use that "right to represent you" email as means to build their credibility. You never know what they're sending "clients" or if they're even sending anything on your behalf. Not sure if they do anything with your personal info, but conversation with them is a waste of time.
