Dear Mr. Smith,
Thank you for your employment offer to be an Assistant Director with XYZ, Inc. Unfortunately, I am writing to inform you that I am unable to accept the offer. After evaluating all opportunities available to me, I have decided to accept another position in a different field.
I truly enjoyed meeting and speaking with you and other representatives from XYZ, Inc. and learning firsthand about your experiences. Best wishes for the continued success of XYZ, Inc.
Thank you again for your consideration.
Sincerely,
Laura Craft
