Thank You Letters
Thank you letters are a must in the job search process. Letters should be sent within 2 days after the interview. However, send the letter even if you lose track of time. A late thank you note is better than no note at all. If you have decided that you are no longer interested in the position, it is still a good idea to send the thank you note. You never know when you may need to contact that employer in the future.
Thank you letters may be handwritten, typed, or e-mailed; it's a personal preference. If you think a decision is eminent you may want to get the thank you in the hands of the recruiter as quickly as possible.
If you meet with more than one person during the interview process, it is best to write each one a personal thank you note. Try to individualize each letter by writing something you learned or discussed. This makes a very favorable impression.
