Preparing for Old Mission Capital
Every firm on this board screens on the same handful of skills: fast mental arithmetic, expected value, probability under time pressure, and being able to explain your reasoning while someone pushes back. Outcry drills those as timed games rather than reading. Internship and graduate candidates face the same screens, usually with a harder cut-off because there are more applicants per seat.
