An interview call letter is a formal invitation sent by an employer to a candidate, informing them about their selection for an interview. It includes essential details such as the interview date, time, location, mode (in-person or virtual), and any necessary documents the candidate needs to bring. The letter serves as confirmation of the interview process and helps candidates prepare accordingly. It may also include instructions regarding assessments or specific interview formats. Receiving an interview call letter signifies that the candidate has successfully passed the initial screening process and is being considered for the position based on their qualifications and experience.
