You should make a policy to never send a resume without an agreement in place, but sometimes it seems like you’ve got to prove you have a product before a client will take you seriously. You need to establish additional value and push for an agreement prior to any resume activity. You can also push to confirm an interview for a date and time that can be cancelled by the hiring authority if, after reviewing the resume, they deem that candidate not suitable. People are not resumes – and you’ve got to make sure you can represent your candidates well enough that you can accurately represent their personal and professional goals more so than is on a resume.
