Marshall Wace Interview Process & Prep

Marshall Wace: London-based alternative investment manager (quantitative, systematic and fundamental strategies, mostly long/short equity); its quant and systematic platform is TOPS.

Per candidates and MW guides: a proctored test (in person at a Pearson centre this cycle; earlier internship cycles: online Codility, technical, data exams). Then a Human Capital screen, data Lab interview or technical project presentation, and an in-person assessment day (brainteasers, case study, code review, manager meetings). Varies by cycle and track (Quant Associate, Quant Internship).

The Marshall Wace interview funnel

1. Initial Test (proctored exam)

~2 hr - in person at a Pearson test centre (current cycle); reports vary

Candidates report, and MW's guides confirm, a timed technical exam first: 2 hours in person at a Pearson VUE test centre this cycle. Below: every bank problem candidates have tied to Marshall Wace.

Pearson's page: 18 questions, negative marking (+2 correct, -1 incorrect, 0 unanswered). MW's topics: probability, statistics, regression, algebra, matrices, optimization, algorithm design. Earlier internship cycles: three online tests (60-minute Codility coding, 60-minute CorrelationOne technical, 45-minute CorrelationOne data); some Glassdoor reviewers describe a longer maths test plus Codility and a data test. Reports vary.

2. Human Capital Screening Call

15-30 min - Zoom (reports vary by track)

After the test, candidates report a short Zoom call with a member of MW's Human Capital team. MW's Quant Associate guide lists 15 minutes and the internship guide 30 minutes. Per the guides it covers motivation (why this role and how it fits your goals), competency questions about past experiences mapped to MW's values, and time for your own questions.

3. Lab Interview - Data Exercise (Quant Associate)

~1 hr - Zoom with a quant; some reports describe 2 hr

First quant-led technical round (Quant Associate), assessing how you work with data, logical reasoning and clear explanation.

MW's current guide: one hour (15 minutes reading, a 40-minute video call on a dataset with a Quant team member, 5 minutes for your questions; Excel, Python, R or MATLAB). Others report two hours: a 60-minute Data Lab in a virtual machine, then an hour on Zoom presenting answers and a signal-construction case.

4. Technical Project Presentation

~60 min - Zoom (internship) or at the assessment day (Quant Associate)

Both MW guides include a ~15 to 20 minute presentation of a past technical project you choose (university assignment, PhD thesis, side project), then questions probing any part for depth. Internship: 60-minute Zoom after the HR call. Quant Associate: at the assessment day with no devices, so bring a printout or send key material at least 3 working days ahead.

5. Assessment Day - Brainteaser Interview

~50 min - in person, two brainteasers

Assessment day in person (MW's London office for interns; one of MW's offices for associates, travel reimbursed where needed). Brainteaser interview: two mathematical puzzles (50 minutes, internship guide), judged on approach, not only the answer. Past example: turn-based dice, crossing out newly rolled numbers; go first or second? Associate days: ~9am start, four interviews, may end after the first two.

6. Assessment Day - Case Study + Programming

2 interviews - in person; the case differs by track

Associate assessment-day morning, per MW's guide. Case study: Quant Researchers build a trading signal with the interviewer, discussing forecasting models and challenges (predictive, quantitative-finance, statistical modelling); Quant Implementation candidates do a system-design case (structure, data handling, component interfaces, performance, trade-offs). Programming: review written code and answer core-principles questions; past example: minimum-cost staircase dynamic programming. Little more case detail exists.

7. Final - Management Interviews + Shadowing

Assessment-day afternoon, or arranged individually

Strong candidates meet managers informally two or three at a time per MW's guides (team structure, management style, fit), and shadow a quant: same afternoon for associates, maybe individually arranged for interns. Some Glassdoor reviewers describe an assessment day of up to six interviews; reviews are mixed. Offers aimed within two weeks, via a Human Capital Zoom on team allocation.
