This is another opportunity to share your skills and the contributions you believed you'd deliver to this position. Prior to your Pfizer internship interview, put some thought into what you feel will be a challenge for you, and come prepared to talk about how you will take that challenge head-on as a growing opportunity. Don't hesitate to offer stories about where you've contributed in the past and how you want to build on those accomplishments as an intern at Pfizer.

"I foresee the first challenge as learning the ins and outs of the Pfizer business and how I can best contribute as an intern here. From day one, I would plan on building great relationships with the colleagues I would be working closely with and take every opportunity to pick their brains. Another challenge for me personally will be finding my niche in the pharmaceutical industry and I admit this is a challenge I put on myself. I would relish every opportunity presented to me at Pfizer to learn and grow as a future professional in this industry."
