Please don't take this as condescending, but congrats on your two interviews! And I mean that. I completely get how disheartening it is to only have a few interviews, and yet, it only takes 1. Of course, we are always more comfortable with more! But my friend keeps reminding me, it only takes one.
Also, don't forget, there's round 2 of the match, where really good sites get left and people match at great places. One of the faculty in my department told me yesterday about how she matched to her top choice and ended up hating it so much that she debated quitting (she's not a quitter!) and her friend didn't match round 1, but matched round 2, and loved her experience and is very successful now. So, while it would of course be an ego blow to have to do round 2, and we might feel embarrassed, at the end of the day no one is ever going to ask you if you matched round 1 once it's all over and done. Plus, we haven't even gotten to that bridge yet, because it only takes one! Congrats again on your two!
