I get asked these questions over and over: "Should I send separate thank-you notes to everyone who interviewed me? Can I just send one thank-you note to the hiring manager and ask him/her to thank others involved in the process?"

The answers are yes and no, respectively.

Send a separate thank-you note to everyone who interviewed you, whether it was an informal pre-interview phone call, an interview lunch meeting, or the final formal interview after a lengthy process.

Don't be stingy with your thank yous!

It's an easy thing to do, it will only take a few minutes--and it will make the recipients feel good about you!

Why wouldn't you jump at the chance to do that?

You can make your thank-you notes relatively short. They can be sent via snail-mail or email.

(There are differing opinions on which is best. I prefer the now "special" touch of a real letter over the routine method of email; others think email is best because it's faster. Just remember that what you say is more important than how you send it.)

Make each thank-you note slightly different by mentioning something in particular that you and the recipient discussed. This is a good reason to do your thank-you notes right away, while the interview is fresh in your mind. You might even want to take notes for this purpose.

Here's a great tip that will really impress the hiring manager: add a P.S. that mentions how helpful someone was, by name. I'm not talking about people directly involved in the interviews; they should get their own thank-you notes. But if there was a receptionist, an administrative assistant, or someone else who was helpful during your interview process, say so. Those people are rarely recognized, but may have influence with the hiring manager. The boss will think of you as someone who appreciates his team, notices things most other people overlook, and goes the extra mile.

Why make this a P.S.? Studies show that most people read the P.S. before (or even instead of) reading the main body of a letter. This P.S. will get attention and impress the reader, which will get your entire letter read and your thoughtfulness remembered!
