I think it should be illegal for companies to post job leads online for jobs that don't even exist. What do you think?

Once, I applied for a job in which I would be working in a bank vault, filing and pulling customers' files. I must have spent at least half an hour, maybe even an hour, filling out the online application. Then I got called in for an interview. So I got myself all dressed up and rehearsed my answers to all the questions I thought they were going to ask me. I was really excited about about this "job". I thought that the interview went very well, until, at the very end, the woman interviewing me said, "Well, if we have any job openings, we'll give you a call." What a big waste of my time. At the time, I was too shocked to even be angry. I didn't really know what to say. I hope I don't ever have to waste my time that way again. Has this happened to anyone else here?
