To provide more context having been on the "other side" during Midyear: My voice was very tired from talking to dozens of people answering mostly the same questions repeatedly. It feels more important as an applicant than it really is, other than determining your fit for a program and how you like the RPD/residents.
For bad or good reasons, I could probably only remember a handful of people afterward. Usually the "good" is having met them multiple times before anyway as it is very hard to stand out in a positive way without showing you researched the program extensively. The bad is more people who interrupted others or asked strange/irrelevant questions. Even the people who asked questions already answered on the website/brochure, which is annoying, were hard to remember because it happens enough. By the time applications come around, almost everyone was forgotten unless the program decided to keep tabs on people. Most do not or just (maybe) give you a point for checking into the booth.
