R3 here -- no interview call.
Also, at Super Saturday, the admissions representative said that the interview will say "to do" for everyone -- whether or not they intend to interview. It's apparently a glitch in their system and they're working on it. Sorry to be bringer of bad news.
But, looking at the percentages of interviews for past years (if my memory serves me... 75%), it sounds like if you are hovered around their averages (after gmat scores, work experience, etc.), that they'll interview you just to see. Hopefully I'm interpreting that right.
