I've been invited to visit the campus and meet the professor I've been in contact with since the beginning of my application process. My research interests align really well with the professor I've been emailing, but he said that when I visit, he wants me to meet with 5 other professors and the department director.
Should I learn all the research points for every professor, even when they don't align with my interests at all? Should I pretend to be interested in the other professors' works, or say that my research interests don't match with theirs? Do I just stick to general questions about the school in general or how their lab operates?
Just not sure how specific my questions should get for the professors whose work I am not familiar with.
