Steven is correct, there is no vector data in the pdf it a graphic. I exported the page to png then imported it as a bit map, I then used bitmap trace Black/White option Threshold about 90, max noise and max corner fit.
Sorry the cv, svg and zip files were too large, but here's the results.
I also used Inkscape to convert to vectors. I think it did a much better job in this case.
