"Employers are looking for registrars with strong organization, time management, and communication skills. As you'll be responsible for maintaining and coordinating records for others, interviewers will want to know about your ability to make spreadsheets, maintain records, and work with word processing programs. Strong interpersonal skills are a plus, so make sure you bring an enthusiastic attitude to the interview."
