i'm guessing the BMI requirements, at least at this stage, would be that you lie within what is considered underwieght and overweight according to BMI calculations, with a more thorough grilling at the real medical.
During the selection process you do one comprehensive company medical in which they will assess your physical condition, and until then they probably don't look at any medical-related items. You will be grilled in the company medical about almost everything related to your health.
hey can anyone tell me a bit more about the numeracy test in stage two...how hard is it? what sort of questions? what should be studied beforehand etc.?
The questions are not overly difficult but the test will be challenging due to the limited time available. The actual details of this test have already been covered before in this thread, so check it out. If you are keen on preparing for the numeracy test, just do some practice questions that you can find in typical numerical assessments for graduate management jobs.
