If the interviewer asks you any general questions about goals, try to focus your answer on something career-oriented.
"I want to go to graduate school to become a licensed social worker. I'm excited about this job because it will give me more experience in the field. I am also volunteering at a children's shelter. I think that the more experience I can get in the field, the closer I am getting to achieving my goal."
"One of my goals has been to secure employment with a company that offers tuition reimbursement and encourages continued education for their employees. I would like to complete my degree through evening and weekend courses while working full time. I believe that this position will help me to get there."
"I have a goal of being a supervisor in 5 years. I am working toward that goal by taking a supervisory skills course and shadowing leaders in my industry."
