Are you able to describe yourself just in a couple of sentences?

Have you ever wrote a cover letter for your resume?

How to explain just in a few sentences how good you are without been errogant, exadurating and, on the other hand, transfer the right message about "what a big treasure" you are for your future employer?

So, here is mine:) Would you hire me?

Dear Recruiter,

I am a passionate sales marathonist (literally)

During my professional career I have built several sales departments from the scratch, recruited and trained sales teams and performed a significant market share growth in each and every company.

I am a hunter in my spirit and results driven personality.

Looking forward to presenting myself in personal interview.
