<human>: I had a second interview yesterday (first was a phone interview, second was a longer interview plus a presentation with Q and A afterwards). They told me at the end of the whole experience that I should "not freak out" if I don't hear from them until January. Ok, that's long, but this job is a staff position at a University so the explanation was that all of this is subject to university administrative practices. That plus the holidays coming up means it'll take awhile. Not great for me, but perfectly understandable. 

I got an email today requesting a quick phone call for tomorrow... I'm just wondering what this could be about? A question they have, some discrepancy in my application? Likely calling me to tell me they are not going to consider me further? Why wouldn't they just email that to me? I just need some ideas of what this phone call could be about.

Can you give me the gist of the text in a nutshell?
<bot>: Interviewer asking for a "quick phone call" the day after interview. Can I assume it is a rejection? Are there other possible reasons why they could be asking to speak with me?
