It’s a fair question but one that many job seekers dread. Sometimes it feels awkward to explain what you have been doing since you left your job, particularly if you left the position involuntarily. But you have probably been more active during this time than you realize and there is no reason to get tripped up by this question. Perhaps you have been consulting, taking classes, volunteering, or taking care of family. These are all legitimate topics to bring up during the interview.
