That's correct. Most of the time, they would like to know you to know more about your personality. It is very laid back in general. I would recommend looking up their website to know more about their program, the eye institute and how their modules work. I got the president, Dr. lewis, as my interviewer, but I totally didn't know! He actually told the staff not to tell me because he didn't want to give me extra pressure.
I would just recommend dress professionally and show confidence in yourself (not arrogance tho!)
Hope that helps! PM me if you have further Q's 😀
