I shouldn't say it's unfair, it is what it is and I am happy I had the opporunity to interview at Case and still be considered for a spot. But waiting really sucks, and it would be nice if schools tried to minimize applicants' wait.
In response to Myuu's comment, you do make a great point. However, since my interviewer talked a majority of the time, I doubt that it could be discerned whether or not I was a "superstar" or "great at interviewing," even though I believe I built a good rapport with my interviewer. Also, most schools outside of the US interview all applicants over a few given days in a non-rolling admissions process, so it certainly is possible and feasible. Now, whether or not their admission and interview processes are preferable is debatable, but I just want to clarify that it certainly is feasible.
