DRW Online Assessment Prep
DRW screens candidates through DRW technical challenge (quantitative) and Codility (software developers) before any interview. Below: the exact format, what each section tests, and how to practise it in identical conditions until you walk in confident.

The format
What DRW's online assessment actually looks like
The first step after applying, before the Zoom interview.
Timed sections
Most online assessments split into 3-5 sections, each with its own clock. Speed and accuracy both count.
Adaptive difficulty
Modern formats get harder if you answer correctly, easier if you struggle. Your final score reflects what you can actually do under time pressure.
Pass mark
DRW sets a pass mark per test type. Below it, you don't progress regardless of how strong the rest of your application is.
Completion window. Taken at home under timed conditions; the invitation email gives the length.
By division. Quantitative trading and research: a quantitative challenge focused on probability and logic. Software development: a Codility coding test.
The provider
What DRW actually buys
DRW configures its own selection of DRW technical challenge (quantitative) and Codility (software developers) modules. Below: the exact products in the suite, why they were chosen, and what the provider's reputation is across the candidate pool.

Section breakdown
What each part of the DRW assessment tests
Each section has its own format, timer and trap pattern. Worked examples below show exactly what you will see and where candidates drop points.
Quantitative technical challenge (trader and researcher)
6 problems · Expect about 45 minutes
What it tests. Probability and statistics: Markov chains, Bayes' theorem, random walks, combinatorics and distributions
Common traps. Leaving the camera frame, if the sitting is proctored.
How to handle it. Set up each model before you calculate, and give answers in the form each problem asks for.
Codility coding test (software developer)
What it tests. Correctness and performance of your code
How to handle it. Test your own edge cases and watch the complexity the inputs need.
How to practise
Drill the skills DRW's test measures
DRW uses DRW technical challenge (quantitative) and Codility (software developers), a format we don't imitate. These practice tests drill the same underlying reasoning skills, timed and scored, so the day-one experience still feels familiar.
- Core-skills practice. Numerical, verbal and logical reasoning at graduate level: the skills under DRW's test, without pretending to be its interface.
- Provider-true difficulty. Item difficulty mirrors the band the real tests sit at, so your score means something.
- Coaching, not just a score. "You are spending too long on table-data questions" beats "you scored 68%". Specific advice per weak section.
- Percentile benchmarking. Your score placed on a modelled US graduate norm curve, so you know if 70% is excellent or worrying for that test.

Time management
Five moves that protect your score
- 01Set your own clock per question. Divide section time by question count. Move on when you hit your per-question budget, even if you are mid-thought.
- 02Read the question before the chart. Half the work in numerical is finding the right number in a table. Knowing what you are looking for cuts the time in half.
- 03Use "Cannot Say" generously. Verbal reasoning rewards strict reading. If the passage does not say it, the answer is "Cannot Say", not your own inference.
- 04Skip the impossible ones. Most tests do not penalise wrong answers more than skips. If you cannot see it in 20 seconds, flag and move on.
- 05Practise the exact format, not a generic stand-in. DRW technical challenge (quantitative) and Codility (software developers) has its own rhythm, and a generic reasoning test is not the same. Intervyo's simulation is calibrated to this format, so you rehearse the real thing under real timing rather than a generic aptitude set.
