The interviewer wants to hear that you talk positively about your past employers. Pick your favorite aspects about your past 1 or 2 jobs, and share these with the interviewer. Maybe you enjoyed working in a school and being around the kids. Maybe you enjoyed the camaraderie with your co-workers. Perhaps you really liked the flexible dress code and hours. Whatever you enjoyed, tell the interviewer that you had positive experiences with your past employment, and share it!
