Dear Mr. Smith, I want to thank you for the opportunity to interview for your company. I hope that you are able to see from my credentials that I would be a good fit for your company. Thank you again for meeting with and discussing a position within your company. Sincerely (Your Name). Now even though this is just a short version of a thank you letter, your should have a little bit more detail in the body of it.
