It typically includes details such as the date, time, and location of the interview, along with any necessary instructions or documents the candidate needs to bring. The purpose of this letter is to confirm the employer's interest in the candidate and provide essential information to ensure a smooth interview process. It may also mention the interview format, whether it will be conducted in person, over the phone, or via video conferencing. Additionally, the letter can include details about the interview panel, expected duration, and any assessments that may be part of the selection process. A well-structured call letter helps set clear expectations for the candidate, ensuring they are well-prepared and confident before attending the interview.
