This from my good friend who works for an international recruiting company….
1. don’t ever pay – the corporation pays the recruiting fee
2. don’t ever give anyone your personal information like drivers license, ssn – resumes only
3. recruiters normally only screen and pass on your resume to the hiring company and the company contacts you from there – sometimes the recruiter will act as a mediator through the hiring process as they are often hired for translation purposes, but they shouldn’t be the only person you have contact with.
