Day Zero

In human resources, Day Zero refers to the time between when a job offer is accepted by a candidate and when they begin their first day on the job. It could be days or weeks long, but it is considered important because it lays the foundation for the new employee's experience. Common events that occur during Day Zero are filling out new hire paperwork, sending important information about what to expect on the first day, welcoming the employee from their team or with welcome gifts or "swag," and possibly assigning a "buddy" or mentor to help the new employee when they begin.
