"I believe that this interview has been quite informative and I am happy with my performance. I greatly appreciate that you have informed me of all of the details of the role and your future outlook for growth for the person that is hired. Is there anything that I can clarify for you from this conversation?"

"When asked about my future career goals, I don't think I was able to accurately portray my vision to you the first time around. In hopes to make this clear to you, I consider myself to be like a ball of clay that will continue to be molded throughout my career. I am open to taking my career in many different paths on the research side of things and I think a start at Johnson & Johnson would provide a world of opportunities for me. I certainly hope this makes sense to you. Other than clarifying this, I feel great about getting to know you and Johnson & Johnson as an organization from our time together. If there is anything more that I can clarify for you, I would be happy to do so."

Be honest with the interviewer about how you feel the interview has gone so far. If you feel you're knocking it out of the park, say so by being as modest as possible. If you feel you've left out any relevant information, be sure to mention it.

Never ask them how they think you are doing. This defeats the purpose of the question. Answering a question with a question is not wise in an interview.
