I have sent several applications over these months for different companies and contractors. Usually I sent the resume in PDF format.
I'm curious and at some point also a little bit upset when recruiters request my resume in doc format. If a change is needed I can do it myself and send it back. But to send the resume in doc format I felt at some point like weak/vulnerable. Is there really a foundation in such feelings or is just my mad brain thinking to much on it?
My point is they can be submitting my information as signed by me but modified by someone else. And finally sounds like you are not being treated directly by the person interested. Sounds like there's a chain of contractors before You arrive to the direct client. And that's a terrible deal.
The recruiters that I have asked said me is a requirement for the submission.
I would try to avoid this practice , I think next time someone request my resume.doc I will think it twice before submit.
