Interview policy

Can someone summarize the interview policy for the following colleges:
NYU, Columbia, UPenn, Cornell, Harvard, Yale, Northwestern, RPI, Stonybrook, John Hopkins

<p>NYU does not offer inteviews, Columbia cannot guarantee that you will get an interview, UPenn cannot guarantee that you will get an interview, JHU cannot guarantee that you will get an interview, you sign up for an interview for Northwestern. I have no idea about Harvard/Yale/Cornell/RPI/Stonybrook, although I suspect that all teh Ivys have similar procedures. They will contact you for an interview.</p>

<p>Harvard and Yale make an effort to interview every applicant.</p>
