My DH applied for a position suggested by a companies HR person. So he did and she lined him up with an interview today. He just got back and tells me that there was no opening and the HR person should have known that. AUGH!!!!!!!! BTW, this HR person is an old friend of mine and IF she did know, she could call the house anytime to tell him not to bother.
It's a shame he wasted his time. Unless you know otherwise, give the HR person the benefit of the doubt that she made a mistake. There may actually be a job opening but management already has someone in mind to fill it.
