Looking at your resume, I see multiple gaps between employment. What were you doing during those gaps?

There are many reasons for having a gap in your resume, and it's best to be honest and upfront about the reasons. Gaps are okay to have so long as there is a legitimate reason behind them. Also, show the interviewer that you did not remain dormant during that time. Talk about any courses you took, volunteer work you did, or any lucrative hobbies that filled your time.
