How to write a letter of interest
Think about skills you possess that you will be able to use at this new job.
Some of these should already be listed on your resume, but in your letter of interest you'll want to emphasize everything that you can possibly bring to the table.
Explain your purpose immediately upon beginning your letter.
Tell your reader how you became aware of the job opening and express your desire to fill it. Keep it short and sweet-this reader may have already seen dozens of letters of interest that day, and you don't want to bore them.
