When candidates go on the job market, they rarely just apply for one position. Usually you want to apply for many positions to give yourself a greater chance of obtaining a position or to ensure that you will have several offers to consider. However, when you do decide to accept a position before you have waited to hear from all of the companies involved, you have an obligation to withdraw your applications from the other companies.
Begin your letter by typing your address. Skip a line, and type the date. Skip an another line. Type the contact person's name, his company name and the company address. Skip an additional line.
Type "Dear Mr./Ms. (Last name)" followed by a colon.
Give the news immediately. For instance, if you have accepted another offer at a different company, state: "I apologise for any inconvenience that this might cause, but I must withdraw my application from consideration. I have accepted a position at another company." You do not need to explain further or identify the company.
Thank the recipient for his time and consideration. If he interviewed you or flew you out to their company for a site visit, briefly express appreciation for that hospitality. If applicable, express admiration for the company and the position. Keep this section brief and sincere. If you did not have a good experience or if you are withdrawing your application in the preliminary stages of their job search, simply thank the recipient for his time and omit the rest of the detail.
Close the letter by typing "Sincerely," and skip three line spaces. Type your name. Print the letter and sign above your name in blue or black ink.
Keep the tone polite and professional. Connections are everything in many positions, and you never know when you will encounter someone again.
