Before they invest in your educational and professional development, your interviewers need to know that you also plan to invest in yourself. Temple University's Professional Development webpage states, "The Office of Student Affairs offers career counseling support both while you're a student and after graduation. Throughout the academic year, guest speakers are invited to discuss a broad spectrum of professional opportunities. Events include programming related to corporate and private practice careers, debt management, general practice residencies, military service, and special education."
A self-development plan is essential for anyone, no matter their future profession. The interviewers want to know your plan and how attending Temple University School of Dentistry will benefit that plan. So comb through their student services, come up with tangible actions you would take, and express an interest in taking advantage of those services.
