In a job search, paying attention to the little things is the big thing

I know someone who has her job search figured out. She's identified an enviable opportunity, she knows whom to talk to and she plans to play up her credentials, which include management of some impressive projects and notable connections in a big city far away.

Too bad she hasn't figured out that the holder of this opportunity will stop listening to her as soon as she starts describing how brilliant she knows she is – because he won't care.
