alums?

I've been calling up alums all week long and haven't had much success with these guys.

I've had one VP in Private Banking who was very enthusiastic and pushed my resume to a bunch of places but other than not, not many were truly willing to help. What I really need is for them to send my resume to the HR person who will decide who interviews and who doesn't. Lots of them are open to chatting but not many of them are willing to do any more than that. They all say I've got a good resume and to just keep trying, keep my options open, read the journal etc etc.

Maybe I'm the one who is delusional in expecting every alum to want to help out? What should I really expect from these informational-advice seeking phone calls?
