This may seem like an unrelated question to many, but it does give insight into your maturity, decision-making, and technical interests. Keep this answer brief - try to think of what you liked best about your last job (or current job) and what you liked the least. Do not mention the names of coworkers or supervisors. Topics for your favorite aspects of your job might include general answers such as teamwork, collaboration, and the opportunity for hands-on work. Topics for your least favorite aspect of your job might include a high turnover rate or a company that utilized outdated policies and safety procedures.
