Palpable Score

87
/ 100
Jane Street offers unusually strong early-career access through recurring internships and multiple entry programs, backed by clear pay transparency and high compensation. The strongest signals are hands-on training, mentorship, and real project ownership for interns and new grads, plus benefits that reduce early-career financial stress. The main limiter is that Jane Street does not publish cohort outcomes like promotion rates or internship-to-full-time conversion rates, so outcomes scoring relies on indirect public signals.
