Sometimes, candidates have a gap in their employment history for various reasons. Perhaps you took time off to raise a family, care for ageing parents, pursue higher education, or volunteer overseas. The interviewers are curious why you took time off to see if that will be a continuing habit if hired for the physiotherapy position. Unless the gap was due to a personal issue, such as a mental health crisis, share why there is a gap on your resume or CV and assure the interviewers that you will be a long-term employee if hired.
