Like Brooke, I also had two different recruiters. My first recruiter did not mention LOR forms to me--actually, LORs were never really addressed at all. I took the initiative to have a few of my colleagues write essay-type letters for me. My second recruiter had me send out LOR forms to a few more people, and I specifically requested that these people add a page to the standard form for a personalized letter. So, my completed package contained either two or three free-form letters of recommendation, plus two more letters of recommendation attached to the standard form. I guess my point is that it didn't really matter whether my references were done using the standard form or not--what matters is that I had strong letters of recommendation. If your recruiter is sending out the standard form, be sure to speak with the people doing your recommendations, and ask them to to attach an essay-type letter.
