About six months ago I started work at a new company. Recently they asked me if I could refer anybody, and there is someone I know who I believe would be a good fit.
I talked to this person, and they expressed an interest in getting the referral. I wrote up a reference letter and was just about to send it to our hiring manager, when I realized something: if someone wrote a reference letter about me, I might want to see it first to make sure they don't do any "false advertising". For example, they might boast qualities I don't have, or they might emphasize a different set of qualities than I would have personally chosen to present to a potential employer.
So, should I offer this person the chance to greenlight the reference letter before I send it? Also, is it common courtesy to CC/BCC them on the referral e-mail thread?
