Most of my interview was in regards to my own background specifically (it felt like they knew me, more than I knew myself), but here are some general ones I can remember outside of the usual vision 2020 and contribution to the field of PT stuff.
"What are your best study techniques? Explain to me your thought process as you apply these methods and tell me why/how it works for you."
"I see that you've taken some research courses. Are you interested in conducting research? Are you considering other top research schools like USC (since I'm from CA)?"
"What have you gained from your life experiences thus far that will help you in becoming a good PT?"
Keep in mind that an interview is not like a typical exam where you memorize responses to pre-selected questions. My best advice is to have a picture of these broad areas:
1. current PT issues (state laws, insurance, ethics, etc.),
2. school history/background/why selected,
3. what you gained from volunteer work/extra curricular activities/observation time,
4. know how/words to describe yourself (strength and weaknesses included),
5. life experiences you have gained to make you a better PT or choice candidate,
6. where you see PT headed in regards to vision 2020 and most importantly,
7. why you chose to pursue PT.
Some of those areas can be tough, but if you're confident in your ability to verbally express those areas, you will do great during the interview.
Nervous? Grab a couple of friends/professors/family members and ask them to give you a mock interview and to provide feedback. Choose wisely. Many friends and family will rather save your feelings than properly critique you. Or they do not have enough insight in the field to properly assess you. I recommend asking professors, PTs, those in health careers or is studying for one. It may not be perfect, but their goals are similarly aligned.
Want to get really serious? Video record your mock interviews. Use your smart phone. Were you clear and concise? Did you say everything you wanted to say? Did you sound like you were reading from a script? Cliches? I have seen the most confident of students admit that they needed to work on some things after reviewing their own mock interview responses. These exercises are a great tool to help applicants with speech, confidence and anxiety issues.
Also, during the interview, it is okay to pause and think about the answer before responding. I hate to beat a dead horse, but be yourself. The entire interview process is not as rigid as many people would think. Good luck.
