It is not uncommon for interviewers to ask questions about scheduling during the job interview. They want to see if you will be compatible with the organization's scheduling needs and the unusual requirements that face healthcare professionals. Most people who enter healthcare realize their jobs will have them working days, evenings, weekends, holidays, and overtime when needed, so this question should not come as a surprise. Let the interviewer know if you prefer day or evening shifts or do not have a preference. Also, let them know you can work holidays and weekends when necessary, showing you are a team player.
