Letter of Appreciation for the Interview
This is a very important letter and should be written two days after the interview.
If all candidates interviewed have the same qualities, this letter will distinguish it from the others. Do not write an extended letter, just mention thank you for the time and interest in the interview. Also point out positive situations that you believe are important and will make the interviewer decide for you. In this letter you can also correct any misunderstandings that had not been addressed correctly in the interview. As a final comment, if you are really interested in the position and want to be considered for it, simply say that you want the job and expect to hear from it in the near future. This is a very important point.
