I think this is good advice, but I worry about wasting the interviewing companys' time. Of course in my experience they rarely worry about wasting my time, but I guess I'd be concerned about becoming known as someone whose interest in a position isn't trusted.
I suspect that this is my inner Cinderella -- be humble, scrub the floors, and one day my hiring manager will come. I feel like that princess is really hurting my bank account.
