Confirmation of Interview Appointment is a formal document that is used to confirm the date, time, and location of an upcoming job interview. This confirmation document can be sent from the employer to the applicant, or from the applicant to the employer. There are two main types of Confirmation of Interview Appointment: 1. Employer-Issued Confirmation of Interview Appointment: This type of confirmation is sent from the employer to the applicant, usually via email, to confirm the interview details and to provide additional information, such as the name of the interviewer and the dress code. 2. Applicant-Issued Confirmation of Interview Appointment: This type of confirmation is sent from the applicant to the employer, usually via email, to acknowledge the interview date and time and to confirm that the applicant will be attending the interview.
