Tower Research Capital Online Assessment
Tower Research Capital is a major HFT firm whose QT/QR desks run a feature-engineering to model to prediction pipeline that ships to C++ production. The hiring funnel is a Developer OA (75 min, 4 problems) or a wangce (online test) DP set, then a phone screen heavy on probability brain-teasers plus a C++ fundamentals bar. Pipeline: OA / wangce to phone to QR / QD / PM rounds to a C++ production round, where C++ proficiency and probability are the decisive bars.
Quant Researcher / Quant Trader — QR / QT probability screen
The QR (45 min) and QT-intern phone screens lead with probability brain-teasers: coupon collector, multinomial covariance, order statistics, random walks, a branching process, the duplicate-the-dataset regression trap, and combinatorial counting, alongside a C++ fundamentals bar (const / static / virtual / mutable / function pointers) and a streaming DS design. The timed set below transcribes the verified probability and statistics items.
Developer / Quant-Dev — Coding OA (75 min, 4 problems) + wangce DP
The Developer OA is 75 min, 4 problems (difference array, hashmap+heap, scope-stack parser); the wangce variant is HackerRank DP. Auto-graded below.
