There are a lot of things that could be delaying our calls: maybe they're trying a new system to put less pressure on interviewers, or the flu is going around, or the radiator is down so everyone is working in temporary spaces, or a hundred other things. I'm sure they're doing their best. At the risk of sounding too saccharine, I'm just trying to remind myself that I did the best I could and that the only thing I can do now is practice patience and try to stay busy.
