Prop / Market Maker · HFT / algorithmic market maker · New York City

An engineering-led HFT with one of the hardest coding bars in the industry, reports consistently rate it above FAANG.

Difficulty: ●●●●●Recruits in India

HRT is a low-latency market maker where coding and algorithms dominate every engineering track. The bar is high: candidates repeatedly describe the coding rounds as harder than FAANG.

Math rounds pair with it, probability, statistics, and Markov processes under time pressure.

Roles they hire

Quant Researcher · Algo/Core Engineer · Software Engineer · Quant Trader

Interview processas publicly reported

  1. 1

    Online assessment

    HackerRank-style timed test, ~2–3 hard problems (LeetCode Medium–Hard, tight limits) blending coding with quantitative reasoning.

  2. 2

    Technical phone screen(s)

    Split into (a) math/probability (EV, conditional probability, brainteasers) and (b) live coding in a shared editor.

  3. 3

    Onsite (~5 rounds)

    Deeper coding (C++/systems for Algo/Core Engineer), probability/statistics/Markov under pressure, strategy games, and Python data-analysis rounds.

What they test

Prep tips

  • Grind LeetCode Medium/Hard and Project Euler under strict time pressure (simulation, combinatorics, clean data processing in C++/Python); narrate while coding.
  • Pair coding fluency with quant fundamentals (EV, conditional probability, Markov chains).

India recruiting

Mumbai office (BKC). Targeted IIT campus recruiting is likely but was not explicitly confirmed in public sources.
