mail from an outsource company

I got a call from a company called SIEGO Outsource Management pvt ltd. I was told that they will arrange interviews for jobs in countries like Canada and Australia. I got an email as well where the process was mentioned like this. -A: Technical Evaluation Step-B: Career Counseling Step-C: Sign Up or Visa Processing Step-D: Job Placement Progress In technical evaluation they are asking for a certificate of graduation, Resume and pan or passport. They said they got my profile from my job. Should I submit my documents or leave it.
