But why?

But Why?

Interviewers do not stop at the first answer. Work through chains of follow-ups on accounting, EV, DCF, WACC, LBOs, M&A, markets, asset management, wealth management and payments, and learn the reasoning behind every answer, including why the wrong ones are wrong.

Online assessment prep

Banks, trading firms and consultancies often screen with game-based tests before any interview. Practise the formats here until they feel routine.

Arrow Focus

Press Q or P for the direction of the middle arrow while the others try to distract you, and hold still when you see crosses. Too early or too late both count against you.
