A problem with this experiment is that while Bill may be the same person in Interview A and B, the interviewers are not the same person. You can't know for sure if the VP in A would act like the CEO in B if Bill was interviewing for a managerial position. It is just as likely that the VP in A is simply a jerk who tries and one-up all interviewees, regardless of the status of the position they are interviewing for.
