Samiya I'm not doing an on-campus interview for Kellogg so it may be different here, but I have done them for two other schools. I would guess that interviewer assignment occurs fairly close to the actual interview, since both interviewers seemed to be reviewing my resume for the first time when I sat down with them.
Again, Kellogg may be different, but I don't think it's possible to get that information prior to the interview (certainly not 2 weeks prior).
Hope this helps! Best of luck with your interview!
