Re: Caltech interviews, they sent a schedule with around 50 people on it, but I can't tell whether they are all chem bio applicants like me. I highly doubt they will admit 50 people but it was such a short interview that I have no idea how they are going to distinguish between people...
My interviewers said they hope to make decisions sometime next week, but they don't really know exactly when. Visit weekend is in early March, so at least sometime before then
