Well you never know about last minute positions. I would certainly tell her to try and get in touch with the people doing the hiring. It pretty difficult in any corporation to get past the hr dept, but who knows.
If you read back in the old posts you’ll see that the most effective way to get a foot in the door is to attend the job fair in April and then keep in touch with the hiring managers.
That’s not to say that there aren’t numerous people who get hired at the last minute because someone dropped out or didn’t pass the physicals. Tell her to be persistant, don’t give up and be prepared leave within a few weeks if she gets a last minute offer.
