Remind the interviewer of who you are. An interviewer may be seeing ten or more job applicants each day. It is easy to forget who's who. Your thank-you letter helps to refresh the interviewer's memory of you and keeps your application front and centre.

Repeat your strengths. Here's a great opportunity to sum up your qualifications and strengths as they relate to the job. Add any backup numbers or details that are relevant.

Reinforce your suitability for the job. Refer back to something the interviewer said and tie it into your experience.

Restate your interest in the job. Let the interviewer know that you are ready to take on the responsibilities and challenges of the job. Share your enthusiasm for the opportunity.

Clear up any concerns the interviewer may have expressed. If there were some specifics about your experience or skills that the interviewer seemed to be concerned about, address them confidently in your thank-you letter.

Oops, I forgot! Often as you debrief after an interview, you will realize that you missed an opportunity to sell yourself and your ability to do the job. You can add this information to your thank-you letter to cover all the bases.

Try for a friendly, conversational approach. Avoid being too general by making specific references to the interview.
