How Tower Research Capital Interviews in 2026: Process, Sample Questions & What They Score

In candidate reports the test ran on HackerRank, or HackerEarth in one case; two reports do not name the platform. Most had 2 or 3 coding problems, often with MCQs on CS fundamentals, C++/Java/shell, Linux or SQL. One report included 15 aptitude questions, and one SDE-2 test added a React to-do app task with 25 MCQs and 2 SQL questions. Some links stayed open for 48 hours or a week, so candidates picked their own time. One application-engineer test had 5 questions on Linux, log parsing, SQL and a graph problem. Two reports (a March 2022 software engineer loop and an October 2021 campus intern loop) list no assessment at all. Prep sites quote 75 to 135 minutes (QuantVault gives 75 minutes and 4 problems for developer roles; Quantt, TraderMath and TechInterview give 90 to 120; TechPrep gives 90 to 135).

Video call, phone or face to face. Individual reports list between 1 and 4 technical rounds. Each round usually has one or two coding problems plus questions on OS, networking, C++/OOP, DBMS, or Linux and Python for application roles; one campus intern round was a 30-minute Java discussion. In one report, two interviewers asked many OS and computer architecture questions after the coding problem. Prep sites describe these as one or two 60-minute live-coding phone screens where the interviewer changes the problem mid-solve.

Low-level or machine-coding design (Splitwise came up twice), a high-frequency trading system design for a campus intern, and debugging a slow API service. Prep sites add order book or matching engine and in-memory file system designs. Only 3 of the 12 reports list a round like this, so it is not in every loop.

One SDE-2 loop had a round with only puzzles (a balance-and-weights puzzle and a rate puzzle). Not every report has one.

Tower's careers page says there are no gotcha questions or random logic problems, which conflicts with this report.

A discussion of resume, internships, past system architecture and situational questions, sometimes with basic high-level design. Interviewers in reports included a hiring manager, a team lead, a division manager, a senior member and, at one campus drive, the firm's CIO. One of these rounds is labeled an HR round in its report but was a projects and resume discussion with a senior member.

Questions on motivation (why Tower, why finance, why change jobs), strengths and goals, plus compensation logistics. One prep site gives 20 to 30 minutes.

Prep sites describe a final day with interviewers from 2 or 3 trading teams, covering coding, systems, C++ internals and behavioral questions for engineers, and probability, statistics and market microstructure for quant roles. Quantt, TraderMath and TechInterview say 5 to 6 interviews; TechPrep and a second TechInterview page say 4 to 6, and the second page places it at the New York office or virtually. QuantVault disagrees on the shape: it says there is no single Tower onsite and that final rounds depend on the team. None of the first-hand reports describe a super day.

Only prep sites describe this stage, and they disagree on its size and on whether it exists as a single event.

Length varies by role and by team, since QuantVault says each team (pod) runs its own process. Prep sites say the quant track gets a probability and statistics test or screen in place of the engineers' coding test. Quoted lengths range from 45 minutes for a QR phone screen and 45 to 60 minutes for a probability round (QuantVault) to 90 to 120 minutes for the test (Quantt). It is followed by probability and brainteaser rounds and statistics rounds whose content depends on the team. QuantVault also describes a recruiter call where candidates are matched to a team before the technical rounds. An undated GeeksforGeeks account of a campus strategist hire (page last updated March 2023, the candidate's contest wins date to 2012) describes a written test, then 3 interviews on one day of math puzzles and algorithm or proof questions, with eliminations after each round. A June 2026 PracHub report of a US quantitative analyst loop says it had five rounds covering probability, puzzles, computer architecture, networks and OS, but lists no questions.

Prep sites say that after an offer, candidates talk with the teams that want them, and pay and day-to-day work can differ by team. QuantVault instead places team matching in an early recruiter call, before the technical rounds.
