Overpriced, low-impact service if you're a decent writer yourself
It's useful if you have absolutely no experience writing resumes yourself, or are completely lacking time. But it's definitely not worth the price if either of those factors isn't true. My writer used canned phrases and threw them at the top, didn't bother to actually read the resume bullets I had spend weeks putting together for b-school/job applications, and clearly just wanted to be done with the whole thing. This was evident from the initial call where he sounded irritated before I said one word, only to then tell me that actually he didn't have much to change in the bullets themselves (so what was he so annoyed about?). He tried to end that first 20-min call early.
