well 33 percent is based off Ryguys' 50 percent get interviewed.
How do we know 50 percent is correct?
I highly doubt its 50 percent. I was on phone with them, and the guy seemed a litttle confused, but I think he said (because i asked how many get interviewed), last year it was between 1/4 and 1/3 got interviews.
This makes more sense than 50 percent. 1/4 seems too small, obviously, but I think 1/3 is closer to the truth than is 50 percent.
Schools that do invitation only interview, I highly doubt only accept 33 percent of those they interview. The whole point of invitation only is to get the group down to a reasonable number that can then be further adjudicated with an interview. I doubt its easier to knock 2 out of three people based off an interview than it is to accept 1 out of 2. Remember, HBS accepts around 50 percent of those they interview.
Or maybe this is a bunch of wishful thinking on my part.
