I was recommended by a friend who also got his resume written by ResumeGo.
As someone that works as a mechanical engineer, my background is not as a writer, so I thought I'd give them a shot, despite being a bit skeptical about the fact that someone else who's main profession is as a resume writer, can write a resume for me in my very technical field.
After filling my form out, I was assigned to Vincent Zhao, who's background was not in my field. Despite this, he actually wrote me a very solid resume that I find to resemble my best achievements throughout my 12 year career.
All in all, I found this to be a very legitimate service. Both my friend (the one who originally recommended me) and myself, were very happy with what we ended up receiving.
