Yesterday I attended my university's career fair and I'm now in the process of writing cover letters and applying to the companies I talked to online. For one particular company that I'm interested in, I spoke with a representative who was particularly interested in me based on my experience, resume, etc... so I really want to address her specifically in my cover letter, but I foolishly forgot to ask her for her name! She introduced herself with only her first name so I know that much, but it didn't even occur to me until after I'd left the fair that I never caught her last name. None of the handouts she gave me for the company said her name on them, they were all just general info for the company. I searched for her name online, but wasn't able to find anything at all.
So I'm a little unsure on what the best approach to this would be. Right now my plan is to address the cover letter to the head of the human resources department (which I was able to find online) and then mention the recruiter by first name in the letter. Would this be a good idea, or is there a better approach?
