Do you have any additional questions for me about this Pfizer internship opportunity?

"Yes. Can you tell me about the other team members I would be working with? What are their roles? Also, will there be an opportunity for me to be exposed to other areas in the organization during my internship here? I'm willing to help out wherever I can."

You should always have questions prepared to ask the interviewer. Before your internship interview, do some research on Pfizer and write down any questions that you'd like to ask. This is a good opportunity for you to learn about the internship, the company, the team, or anything else you'd like to know, so take advantage of the opportunity.
