No but I interviewed friday and they said january as well. I think they just try to temper your expectations/make you feel better if you don't hear on the first day. By saying I'll hear in January I won't be dissapointed when I don't hear in mid december
I think that January is the most recent that you can hear from them because after you interview, it takes them about 3 weeks for the interviewer to submit their review of you, and then wait for the committee to meet and discuss your file, etc. And on top of that, there is the break. So the people that they are calling in December is the people that interviewed way before and have already been discussed in the committee meetings. So ya, they probably meant that January is the earliest you can hear, but it definitely can be anytime from January on
