Have a question. I realized that I'm probably taking on too many interviews, and it seems like an exhausting and time consuming process. I'll hear back from one of my top choice schools by end of January and all of my interviews come afterwards, so if if things work out I'd be interested in cancelling 2-3 of them. How bad is it to cancel an interview 1) before making travel arrangements 2) after making travel arrangements (e.g. flight)? I would just feel really guilty doing so after the administrators and professors took the time to figure out scheduling, to arrange hotels, etc. but would be really be helpful for my own schedule
