Ask HN: Use Facebook to land interviews?

I'm currently seeking an Internet professional job (Marketing or Web Design). I've sent numerous resumes out & never received an interview invite, until I found names of hiring managers(on company site) and then found/sent them message on Facebook re: jobs. This worked and landed me an interview that went great with her(age 29), but 2nd interviewer her boss (age 47) hearing I did this ended interview. So, would you use Facebook this way or it's going to far?
