I have an interview at my #1 choice coming up. The story is that when I applied to the program, I got rejected. However, I did a rotation after I got rejected, impressed a few attendings, who then spoke to the PD on my behalf and got me an interview. The program is prestigious, and I got along with the residents and attendings very well. I actually exchanged numbers with one attending. When I interview, I want to communicate to whomever I interview with that the program is my #1 choice. How can I do this without negatively impacting my chances of matching there? I do realize that I was rejected initially, so the interview may be a "courtesy" one. However, I did the rotation without the intention of getting an interview and got one. So, lightening may strike twice. Any advice on how I communicate to the interviewers about the program being my #1 choice without adversely affecting how they rank me? Thanks in advance.
