A search on Google of the words "resume first person" (without quotes) will help, with the first 10 answers pretty much unanimously agreeing with my belief. I've explained why in other responses (mostly redundancy - "I did this, I did that" gets old.

This isn't the #1 piece of advice I give in my job. I'm a writer. I write the documents. I'm not telling them what to do.

I do offer review services, which are a small part of my business. If I get a resume with the word "I" for a review, I will tell them what I've told you.

You seem intent on belittling what I do, as if my job is to walk around telling people "don't use I".
