Dont get too worried, for one thing remember its up to students to update their status and I know a bunch of folks if you look at their status still have nothing listed but have known for a while where they are going. I wouldnt be surprised if most schools numbers are significantly better than they appear. I know my section is around 75-80% with offers but plenty of folks havent let the CMC know, especially if they havent decided. Overall I would say we definitely are over 70% but a lot of folks haven't reported, and if you take out people who arent doing anything, going back to family businesses, or starting their own thing it will look even better.
My sense is that the majority of the people still looking fall a few buckets. Those who want something that traditionally doesnt recruit until late in the year (HF/VC, Real Estate, Media etc.), are internationals who still are trying to find something in the US, and then the others (not even looking, sponsored folks, overly focused, unlucky, turned down offers but still looking).
I dont know how effective other schools are at getting students to update their status. Here its all on us to go through the system and some people either dont think its important or dont know they are supposed to do it. So unless schools are actively finding out people status, I bet that the numbers aren't as bad as they seem.
I wouldnt worry if I was going next year, for one thing next year will be better than this year and there are actually lots of opportunities still available at this point in the game. I think Steel mentioned he got 4 interviews lined up at the end of last week alone and some of those sound like really awesome opportunties.
