I have taken this several times, and consistently get ENTJ.
Masterminds are rare, comprising no more than one to two percent of the population, and they are rarely encountered outside their office, factory, school, or laboratory. Although they are highly capable leaders, Masterminds are not at all eager to take command, preferring to stay in the background until others demonstrate their inability to lead. Once they take charge, however, they are thoroughgoing pragmatists. Masterminds are certain that efficiency is indispensable in a well-run organization, and if they encounter inefficiency -- any waste of human and material resources -- they are quick to realign operations and reassign personnel. Masterminds do not feel bound by established rules and procedures, and traditional authority does not impress them, nor do slogans or catchwords. Only ideas that make sense to them are adopted; those that don't, aren't, no matter who thought of them. Remember, their aim is always maximum efficiency.
