if you are local or will be visiting: from the web site go to visit CWRU, the interview times are listed there, you schedule one when you schedule your visit.
Are you on the mailing list? In other words have you officially "requested info". If so, I think you would have received an e-mail when adcom reps were visiting High schools. I am guessing they have finished off site interviews and are firmly in their offices reviewing applications but I could be wrong.
If all else fails, call the admissions office and ask them.
