uh. why did you ask a question in the thank you letter?

you should have made it seperate or eiter asked that question during your interview.

Unfortunately many interviewers will not respond if your candidacy doesn’t continue – regardless of what they may say. However, it may take some time for the interviewer to get back with you. I don’t know the specifics of their process but take in consideration how many interviews they may have conducted (or if they are still conducting interviews), etc. If it is an application for business school I would suggest calling the admissions office about 2 weeks after your interview and asking them “what the next steps are.” I would *not* ask them directly to comment about the state of your application although they may volunteer this information. If they say that decisions have been made, you of course can ask how your application faired.
