At the time of her graduation Julia obtained permission from several people who will serve as references for her. Two years later she is interviewing for a new position and knows that some employers she has interviewed with will be performing background checks on her. In regard to her references she should:
1. Do nothing at this point
2. Send a message to her references letting them know that requests for information will be forthcoming and attach a current résumé.
3. Select all new references.
4. Call each reference to apologize for the inconvenience.
