Majors

Trains you to work precisely in a second language — and, less obviously, to research an unfamiliar subject fast and explain it to someone who does not share your context.

Trains you to model a problem precisely enough that a machine can execute it — and to reason about what happens when it does that at scale, under failure, and with someone attacking it.

Trains you to see how money actually moves through an organisation — and to be the person who can say whether a number is defensible.

Trains you to study human behaviour without fooling yourself — designing a question that could come back with an answer you did not want.

Trains you to find out what is actually happening, verify it, and explain it to people who were not there — on a deadline.

Trains you to price time and risk — what a future cash flow is worth today, why two assets with the same expected return are not the same bet — and to read how institutions actually move money.

Trains you to take a messy situation, find the rule that governs it, and argue to a standard where someone who disagrees has to answer you rather than dismiss you.

Trains you to make a visual decision on someone else's behalf — what a stranger sees first, reads second and feels about it — and to defend that decision in a review.

Trains you to work out who buys, why, and what would make them — then to spend someone else's money on that guess and be measured on whether it was right.

Trains you to keep a person safe through the hours when no doctor is in the room — to notice deterioration before the monitor does, and to act inside a protocol while still exercising judgement.

Trains you to coordinate work you do not personally do — to read the numbers, split a job into steps, decide with incomplete information, and get people who do not report to you to act.

Trains you to take something you understand and get it into someone else's head — by working out what they already believe, where they will go wrong, and what evidence would show they have it.

Trains you to turn a brief, a site and a budget into something that can actually be built — and to be the person who is answerable when the drawing meets the ground.

Trains you to take a rule written for everyone and work out what it means for the one person in front of you — and to leave a record of that decision which someone else can check.

Trains you to take an undifferentiated complaint from a frightened person, decide what is most likely and what would be most dangerous to miss, and then carry the decision — including when the tools in the room disagree with you.

Trains you to run a place where strangers eat, sleep and complain: the flow of a service, the cost of a cover, the roster that covers Saturday night, and the decision about what to give away when something has already gone wrong.

Trains you to reason about how people respond to prices, rules and incentives — and to work out whether a number showing that response was caused by the thing everyone is crediting for it.

Trains you to run and change systems other people wrote: to find out what an organisation already has, what depends on what, what a record in it is allowed to mean, and what would break if you switched one of them off.
