Many times, especially when we're young, don't know much about the world. We go into an interview thinking, as you point out in the article, I'll wear a good suit.

And more importantly or as importantly, what doI need to do with that research to be appealing to these folks? You give an example in your essay and I think I probably mentioned on the air. The interviewee needs to make the case for why it's good for the interviewer.
