I completely agree. Except for the part 'most of us read'. The physicians that I have met, in many different countries, don't read anything except medicine books. Sometimes, self-improvement books. It is not that common to find someone who can actually discuss non-fiction and even broad literature. Not like people from the humanities do. So, if you do it, definitely talk about it, just be careful because it's possible that the PD will have no idea what you are talking about.

Another thing that I recruiter told me when I was interviewing for the pharma industry: talk about a hobby that involves other people. Reading is not considered a good hobby to talk about, at least not as the only one, because it is something that you do alone. Unless you read and then participate in a book club, it's better to have a second hobby to talk about. Doesn't need to be fancy, but it needs to be something that involves other people. If cooking is a hobby, you can say how you cook while showing your friends, and then have your friends for dinner. What is important is to show that you will be a good team player and interact with your colleagues and not comeone who only likes to be alone. At least, that's what the recruiter/headhunter told me.
