Here is a sample letter I created for you to review and model for your own needs.
My name is Wana J. Bad, and I interviewed with you this past Wednesday regarding the position of Marketing Director offered by your company.
I very much enjoyed talking with you and meeting the members of your staff. I found our conversation to be very insightful and informative. The concerns you expressed about your new employee being aggressive, multi task oriented and extremely hardworking were well founded. Boss Enterprises deserves a future employee who exhibits all of these qualities and more. Mr. Man, I feel my skills and experience would be extremely conducive to Boss Enterprises’ work environment and I would prove to be an asset to your organization. If any additional information is needed please contact me.
