It's polite. It's common sense.

It's a thank you letter, or follow up e-mail after your interview.

The managing editor at "Business Insider" brought this up, she says for some reason people don't do it any more. She goes on to say it makes her assume that they don't want the job, or they're disorganized and forgot to follow up. She says either way, people who forget usually don't end up with the job.

For me, it usually shows the person I'm considering may not know how to deal with people very well. I managed a radio station prior to coming here, I've gone through plenty of interviews (on both sides of the desk) and have seen, and made, plenty of mistakes. Take it from someone who experienced it, send a follow up.

What should the letter contain? "Business Insider" suggests three things:

  1. Thank them for meeting with you.
  2. Say something about how you want the job.
  3. Explain quickly why you're perfect for it.

This not only shows good character, it shows your interested. Give it a shot.

While we're on the subject, I would suggest you read "How To Win Friends & Influence People" by Dale Carnegie, you can get it really cheap on Amazon. It goes over a ton of common sense, personal and business, practices we all forget.

Happy job hunting!
