 **Notes**
 * If there are no interviews with the given date, Tether will simply inform you that there are no interviews found and the displayed list will remain unchanged.

For example, after applying `filter_interviews_by_date 2024-05-05`, and if there exists interviews on that date, you will need to `list_interviews` again before applying `filter_interviews_by_date 2024-06-06`.
