WHY SHOULD YOU WRITE A THANK YOU LETTER?
It will help you be remembered. Gives you an opportunity to restate that you understand your prospective employers' responsibilities. Gives you an opportunity to show a genuine interest in the job. Because most people DO NOT take the time to write a thank you or follow up letter! So be one of the few that takes the time and makes the effort...you won't be sorry.
HINTS for a SUCCESSFUL THANK YOU LETTER
Thank the interviewer for his or her time. Refer to the position you interviewed for. Express enthusiasm about the opportunity to work with this company. Refer to your strengths. Refer to a personal conversation that took place during the interview. For example, “I enjoyed learning about your favorite hobby, fishing. I hope your trip to the lake was enjoyable.” Present ideas or qualities that you did not mention in the interview. State that you look forward to speaking with the interviewer again. Restate the date that a decision will be made. Keep the letter and your thoughts organized. Write a rough draft before making a final copy. Remember, this could be the last contact you have before the employer makes his/her decision. Keep this shorter than the cover letter. One half a page is enough. Write it and drop it in the mail as soon as the interview is over.
