As usual, I encourage you to perform your own due diligence since conventional wisdom is often wrong. However, the following general pattern can be observed for the major consulting firms:
ultra elite cluster- hiring is in the double digits, often several dozen
elite cluster- perhaps a dozen or so, depending on the school
trans elite- a handful
near elite- a few
near elite frontier- perhaps one
local schools- virtually nil
Some uncertainty about your future career is common for applicants. Nonetheless, if you are completely unsure what you want to do, you might to wait before applying to an MBA program.
