After receiving an e-mail or phone call for an interview, you can send an interview acknowledgement letter to confirm the time and place of the appointment. This serves as a reminder to the employer and to you of the interview. Your letter should be short and to the point and written in a professional tone.
Respond by e-mail if your communication with the employer has been by e-mail in the past. This is acceptable, especially if the employer has expressed preference for communication by e-mail or e-mailed you with an offer to interview.
Avoid writing too familiarly to the employer. Address him by Mr. or Dr. in your letter, unless you are already on first-name terms with him, or he signed his e-mail with an offer to interview with only his first name. Address a woman with Ms. and her last name.
Keep your letter to less than half a page. You are only writing to acknowledge the date and time of the interview, not to give your qualifications for the job again as you did in the cover letter.
Write the date, time and place of the interview in your acknowledgement letter. Format the response in a business format with a greeting such as "Dear Mr. Simms." Skip a space between the salutation and the body of the acknowledgement. You might write your response like this: "I am writing to confirm my interview with you on Wednesday, 7th of April, at 10:00 A.M. at XYZ's corporate office at 275 Market Street, Newbury in Room 102. I look forward to meeting with you to discuss my qualifications for the Research Assistant position at that time. Please contact me at 01113 929387 if this information changes or if you have any questions." End the interview acknowledgement by using a professional closing such as "Sincerely" and your full name. Write your signature by hand above your typed signature if you mail your acknowledgement letter through the post.
