After receiving an email 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 email if your communication with the employer has been by email in the past. This is acceptable, especially if the employer has expressed preference for communication by email or emailed 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 email 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 lformat 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, April 07, at 10:00 A.M. at XYZ’s corporate office at 1275 Market Street, Newberry 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 555-392-9387 if this information changes or if you have any questions." End the interview acknowledgment 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 mail.
