To those of you (us) still waiting for R1 interview invitations, I found it extremely useful to check this topic's thread from last year and also to compare the % of gmatclubbers who have received interview invitations from schools with similar acceptance rates (not many as low as Haas, unfortunately).
If you check the thread from last year, you will see that a handful of invitations went out the week after the holiday, January 3-8 or so. In addition, in 2008 R1 about 50% of gmatclub Haas applicants received interviews and in 2009 R1 that went down to about 30%. Also useful, on threads of schools with similar acceptance rates, at least 30% of applicants have been receiving interviews (that number hovers around 50% for highly ranked schools with higher acceptance rates).
However, on this thread, only 6 out of 27 applicants have received interview invitations, below 25%. Therefore, I would like to make the highly scientific conclusion that 4 or 5 more gmatclubbers will receive invitations this week.
*The numbers also reveal that about 5 or 6 of us will be put on the waitlist, with 2 or 3 eventually getting in.
