After a job interview, thank you letters are important because they are appropriate interview etiquette. The purpose of the thank you letter is to thank interviewers for their time and information, add any afterthoughts about your own qualifications, and state your interest in the job. Â Word process and promptly snail mail your thank you letter no later than the day after your interview. If multiple people interview you, write a unique letter to each person because interviewers compare your letters.
The reason for word processing is because you have an opportunity to show off your business writing skills.  Don’t miss this opportunity to give interviewers one more reason to choose you for the job!  The reason for snail mailing is because you have an opportunity to put a piece of paper with your name on it in front of an interviewer as a visual reminder of who you are; otherwise, an interviewer can easily delete your email.
During an interview, ask when the interviewer plans to make a decision.  If the decision will be in the next few days, attach your word processed thank you letter to an email and send it as well as snail mail your letter.  In your email state that you want to ensure the interviewer receives your attachment before making a decision.  By the way, to find out the interviewer’s email and address, during the interview, ask for the interviewer’s business card.  If you know interview etiquette and send a thank you letter (with every word spelled correctly) and your competition doesn’t, you just enhanced the probability of an interviewer choosing you for the job!
