When I did the interview I was 181 cm 104 kg (so that's BMI just over 32) and the doctor (forget his name, but very nice english chap who I believe is the chief doctor for CX) didn't seem to have a problem with it or give me any hassle.
No I didn't get the job either, but I suspect that's probably more to do with the fact that I flew the simulator like a steaming pile of merde
