Seriously, why do you advertise positions if you're not going to hire until "in a few months"? The impression that you're making on applicants is that you're just fishing for resumes. Please consider that applicants put time and effort into preparing a cover letter and their resume. If that's how you treat applicants, I wonder how you treat employees?

Sadly, you're not the only one in the industry who behaves like this. I experienced exactly the same thing with Mozilla this year. I welcome that hokua is making this public because that way of treating applicants should really be outlawed.
