Remember these tips:

• All letters should be standard business format, either typed or hand written on professional business note cards or paper
• If you choose to email your thank you letter (still send the hardcopy), the subject line should read "Thank you for your time".  Still follow the standard business letter format including name, address, title etc.
• Thank you letters should be sent within 24 hours of the interview.
• The letter should be addressed to the person with whom you interviewed by name and title. (You should have asked for a business card during your interview. Now you will be sure to have the correct spelling and title of the interviewer)
• Be sure to send separate thank you letters to each person you've met.
• Check for any spelling errors.

Be sure to include:

• The first paragraph should include a general appreciation for the interview. Include the position you interviewed for and the date of the interview.
• Within the second paragraph discuss what you can bring to the table. Parallel examples from your background to specific duties the job will include.
• In conclusion, end with a final thank you, a positive statement and your eagerness for the next step in the interview process.
