Was asked to describe my Master's research project, and then was asked some questions about PCR. I also had to prepare a 10 minute presentation about an invention during my lifetime I thought was significant, explaining the invention and its benefits for society. The interviewers were very personable, and prompted me whenever I stumbled or was uncertain how to answer their questions. They also provided me with personalised feedback in a timely manner. Though I didn't receive an offer, I would certainly reapply and the interview gave me a very good impression of the company.
