    A Jane Street Software Engineering Mock Interview with Grace and Nolen

    Grace, Nolen, Nolan, Emily Fortuna, Colton Ogden, Todd Kerpelman, Jen Person, Colt McAnlisley, Dan Galpin, Mark Mirchandani

    Nolan and Grace, experienced Jane Street employees, co-created a mock interview simulation featuring a unit conversion challenge that evaluates a candidate's graph-based algorithm design and problem-solving collaboration. During the session, the candidate developed a breadth-first search solution to minimize floating-point errors while iteratively correcting structural flaws regarding bidirectional graph construction and edge cases. The exercise underscores Jane Street's emphasis on code clarity, effective communication, and the ability to refine logic through dialogue rather than demanding immediate optimization or perfect syntax.

    Textbooks, Tablets and Teaching: Reinventing How We Learn

    Nolan, Roger, Joel, John, Jim

    This initiative drives a fundamental shift in education by replacing static, time-based curricula with dynamic, competency-based digital platforms that accelerate student learning speeds by a factor of ten. Currently deploying across major districts like Los Angeles and Guilford with millions of students, the program addresses critical infrastructure gaps through FCC E-Rate revisions and transitions funding models from textbook contracts to flexible technology packages. By enabling real-time curriculum updates, personalized assessment, and external skill validation, the movement aims to dismantle traditional barriers to graduation and prepare a globally competitive workforce within the next decade.
