What's the proper etiquette for responding to a post on LinkedIn from somebody (an alum of my school from several years ago) looking for a graduate of my school to fill a position? It says very little about the position, just that it's quantitative research in education. Do I send a cover letter/resume? Or is a paragraph about myself with my resume sufficient? It's hard to tailor a cover letter to a job you know very little about... Maybe just send my standard form cover letter?
