Ironically, a negative review here is part of what inspired me to buy a resume from resume writing group and I'm glad I did!
Someone was whining that they submitted "200 resumes" online electronically and only got 4 job interviews. I found that ironic because knowing that thousands of people submit to most online job posts, I believe 4/200 is a pretty good callback/interview rate especially when considering 1) this person is probably exaggerating their claim of 200 submissions anyway and 2) it doesn't sound like they let that much time pass between ordering a new resume and deciding it's not working out.
Having sent my own resume out to 80-100 online posts last year and getting only 1 questionable interview, I was intrigued to have the resume writing group help me.
I sent the resume they wrote for me to precisely 125 places online and I now have 5 interviews lined up! I'm happy with that result. Whether I get hired now is up to me, not them... but clearly, I'm doing better with their help than I did without it.
