An exit interview is an activity that allows a departing employee and their organization to exchange information, usually on that employee’s last day of work. Typically the exit interview is an opportunity for the employee to explain their reasons for leaving and provide feedback about their experience working for the organization. This exchange could happen in a face-to-face interview between the employee and a manager or HR, or it could simply be a survey which the employee fills out and turns in. For the most effective communication, the first option would be better.
