I would be more than willing to address the original question, being a current resident at said program.
We (the residents) made a concerted effort to be upfront and honest with our applicants in regards to our second year. Yes it's hard, but seeing as how the second year is harder than the other years at pretty much every program, I can't honestly say we are harder (that's what she said) or easier than any other program. I do know that as a second year, I wasn't here past 12 post call and I got 4 days off a month. Clinical duties were done by 5-6pm most nights, and I rarely came in earlier than 6am. Our PGY-2's take only 5 calls a month, though they are mostly Fri/Sun calls. There is a quite extensive anatomy program that involves a detailed dissection and weekly hour presentation for 10 months of the year. In addition, we have weekly case conference presentations by attendings/residents, at which the PGY-2s are expected to present as well. The reason we tell everyone that comes to interview that it is hard is not just for your benefit. Our hope is that pansy med students, recognizing they aren't interested in working hard, rank our program low and then won't match. Now if you don't mind one tough year, our program then offers a tiered call schedule and seniority perks that make the other years quite beneficial towards operative experience and education. If you're a resident who likes to work hard, not complain, operate PGY 1-5 years, drink beer, and aren't offended by continuous resident office flatulence, then you'll probably fit in.
In response to the second question: we do offer most (in rare instances we won't) of our rotators interviews. We interview around 70-80 people a year for 5 spots. As has been mentioned in numerous other posts, rotating can help and hurt. If you're a bad rotator, then you ruin your chance to match at that program. If you're a great rotator that the residents like, then your opportunity to match at that program is pretty signficant. There are only suble clues on interview days that alert residents and attendings to a potential applicants douche-baggery. Thus, it is often a safe bet to choose a rotator who worked hard for a month and is known to everyone over a potential douche bag. I would find it hard to believe that isn't the case at every single program in the country. With that said, if an interviewee comes and impresses the group, then they have just as good of a chance to be ranked to match.
Again, if you're worried about working hard as a second year, please do yourself and all ortho programs a favor and match into your radiology backup position.
