as per some of my other posts, I would be careful about what you post on your CV. Yes, you shouldn't over analyze things and such, but at the same time, be careful. You should pick hobbies/interests that you have that would fit in well with most of the ortho crowd. This is how they will remember you, because it is usually the only interesting thing on someones application, because they have seen it all.
For instance (and this is a huge hypothetical) say one of your interests was "Going to strip clubs".
This may be something you truly enjoy. In fact, it maybe something that many orthopods may enjoy.
But, I'm sure everyone would agree, that's not a good interest to put down. Why? Well, that's up to you why, but this is an unambiguous situation.
Now, for instance, last year (when I didn't match,) I put down surfing. Almost everyone on my interviews asked me about that. Now, I'm sure a few of them truly were interested, and thought it was different, but at the same time, how many ortho programs do you know of that are in close proximity to surfing? Very, very few. So naturally, they thought, and they asked, "Why do you want to come here...if there is no surfing?" Sure, you may have a killer answer to reply with, but that initial impression will not be changed in their eyes. In the end, it may make the difference between one or two ranks, which can make all the world of a difference. I know, sounds melodramatic, but seriously, this is important.
They could have also decided that it was a negative thing that I was a surfer. Why? Because in the past suring was not considered a real sport, but a hobby for the lazy 'california dudes' or some bogus thing like that.
Nevertheless, you can see how something can very easily be turned against you or used to bump you down a few ranks. Several attendings have agreed with me on this, and recommended that I do not put that down on my CV.
Trust me on this one! Sometimes I truly feel the reason I didn't match the first time was because of this, I really do.
