WorldQuant Online Assessment
WorldQuant's screens are coding-centric and role-split. The Software Developer and Data Scientist tracks run timed HackerRank OAs (2 coding problems plus a short CS-concept MCQ section for SDE; 4 performance-gated problems in 120 min for DS, one of which must be C++). The Quant Researcher track instead opens with a timed Math Test (probability, statistics, calculus, mental math), and the distinctive BRAIN / Alphathon path recruits alpha researchers who must speak fluently about alpha and how to measure it (IR / Sharpe, turnover, fitness, out-of-sample stability). The pipeline then moves to coding and researcher interviews.
Software Developer / New Grad — Software Developer
The SDE / NG hiring test pairs 2 coding problems (Biological Hazards, Degree of an Array) with a short section of 4 single-answer CS-fundamentals MCQs (complexity, hash tables, heaps, sort stability). The NG and SDE banks are the same set, differing only by one hashmap-concept item. The concept section is below; the coding half is staged separately and added in a later phase.
Software Engineer / NG — HackerRank algo (2 hard)
The SWE coding OA: 2 hard algorithm problems (two-pointer interval counting, hashing). Auto-graded below.
- Biological Hazards Coding · medium
- Degree of an Array Coding · easy
Data Scientist — HackerRank (120 min, 4 problems, performance-gated)
The DS OA is 120 min, 4 problems where PERFORMANCE is the gate (brute force TLEs) - sliding-window max-of-min, counting pairs, cycle-sort. Auto-graded below.
- Counting Pairs Coding · easy
- Maximum of Sliding Window Minimums Coding · easy
- Minimum Swaps to Sort by Popularity Coding · medium

What is the WorldQuant online assessment?
WorldQuant's screens are coding-centric and role-split. The Software Developer and Data Scientist tracks run timed HackerRank OAs (2 coding problems plus a short CS-concept MCQ section for SDE; 4 performance-gated problems in 120 min for DS, one of which must be C++).

The pipeline then moves to coding and researcher interviews.
What is the format of the WorldQuant OA?
It runs as 3 tracks (Software Developer, HackerRank algo (2 hard), HackerRank (120 min, 4 problems, performance-gated)). Software Developer / New Grad, Software Engineer / NG, Data Scientist — each timed, auto-graded where applicable.
How do I practice for the WorldQuant online assessment?
Work the sample questions above (each with a full worked solution), then take the interactive WorldQuant OA practice on QuantVault. For the full interview, see the WorldQuant interview-questions set.
