I wrote a thank you email to one of my interviewers, and in his reply, he says "good luck with all of your upcoming interviews." Is this good or bad? I'm stressing out. Also, in that same interview, I accidentally fudged while discussing my research...minor point in protein structure, but he does research in the field and was like "oh really? I didn't know that." What do I do? This is a school that cares a lot about research. And the mistake is in my wording...I didn't clarify so it might have been taken for something else. Can I rectify this somehow? or it shouldn't matter? Thanks guys!
