Hello,
When Texas Tech asked me this earlier this month, the question was worded by the interviewer as follows: "So <insert name>, please take a few minutes and tell us about yourself, about your hobbies interests, maybe what pushed you towards pharmacy?"
And I answered with telling them my full name, where I currently went to school. Then in order to make my answer less dull and a little more unique, I stated a personal motto I live by.
Then, I went on to say where I was born, lived, grew up, and along with that explained where my interest in science began and how it grew into an interest in pharmacy (and I didn't at any point give the cliche "I want to help people" nonsense, I gave them legitimate and honest reasons). I emphasized that I had had a wide variety of jobs (mostly retail) and some community involvement activities that allowed me to develop a number of skills that were salient to the pharmacy practice.
All in all, I probably took about 3 1/2 to 4 minutes to answer this question and was sure to always look squarely into the eyes of the interviewers (of course). I was also concerned about giving them what might seem like a preconceived answer if I elaborated too much on my interest in pharmacy or community involvement activities. However, the interviewer did ask me to mention it somewhat, so I did. I hope this helps.
