Headlands Technologies Online Assessment
Headlands Technologies runs two kinds of first-round OA.
Engineering-style candidates get a timed coding screen heavy on data-structure design and streaming or order-book problems (top-K by notional, as-of joins, max concurrent orders).
Quantitative Researcher new grads report (September 2026) a single 70-minute webcam-proctored sitting in four timed blocks:
- 10 statistics multiple-choice questions in 10 minutes, where an answer counts only if you tick exactly the right boxes
- 4 free-response statistics problems in 24 minutes
- 1 C++ problem in 20 minutes
- 2 coding problems in Python, Java or C++ in 16 minutes
The two statistics blocks have timed replicas below.
Practice every firm's OA: timed replicas, free game replicas and guides in one place →
Quantitative Researcher (new grad) — Statistics multiple choice (select all)
Ten statistics and machine-learning vocabulary questions in ten minutes, several of them select-all-that-apply with all-or-nothing marking: estimator bias and consistency, regression assumptions, p-values, distributions, regularisation, cross-validation and time-series basics. The replica draws a fresh mix of ten from a larger pool on every run.
Quantitative Researcher (new grad) — Statistics free response
Four longer worked statistics problems with typed numeric answers: least squares from a small table, a maximum likelihood estimate, an interval or test statistic, and a conditional expectation or order statistic. About six minutes each.
Coding — C++ and algorithm problems
The QR sitting ends with one problem that must be written in C++ and two more in Python, Java or C++; engineering candidates get a longer coding screen built around data-structure design and streaming problems such as top-K by notional, as-of joins and maximum concurrent orders. Warm up your C++ before the sitting.

Quantitative Researcher new grads report (September 2026) a single 70-minute webcam-proctored sitting in four timed blocks: 10 statistics multiple-choice questions in 10 minutes, where an answer counts only if you tick exactly the right boxes; 4 free-response statistics problems in 24 minutes; 1 C++ problem in 20 minutes; 2 coding problems in Python, Java or C++ in 16 minutes. The two statistics blocks have timed replicas below.
What is the format of the Headlands Technologies OA?
It runs as 3 tracks (Statistics multiple choice (select all), Statistics free response, C++ and algorithm problems). Quantitative Researcher (new grad), Quantitative Researcher (new grad), Coding, each timed and auto-graded where applicable.
