Follow-up after an employment interview can be pivotal to getting the job. A thank you or letter of appreciation can be very effective to "closing the sale," -- and always refer to the position discussed. Below is one of several possible follow-up letters.

Dear Ms. Murphy:

It was a pleasure to meet with you last Tuesday. Our discussion about the qualifications for the Customer Service Representative position only served to convince me further that I am right for this job. The people and the environment at your company were so welcoming and friendly, I could imagine myself as part of your team. I hope you can, too. Once again, thanks for your time and consideration. If you have any questions, feel free to call me at any time.
Sincerely yours,

John Richards
