The XTX Markets Take-Home / Technical Data Round interview is stage 3 of 6 in the XTX Markets interview process, after the Recruiter / First Technical Screen. Format: Multi-hour take-home or live technical · researcher-heavy. Researchers commonly report a mid-funnel take-home: an open-ended statistical / ML problem on a dataset (model-building, data analysis, or a more theoretical ML question).

What the Take-Home / Technical Data Round tests
Engineering tracks may get a longer technical coding exercise instead.
XTX trades tiny, fleeting edges, so conclusions must survive live data. Deliver colleague-ready work (clear structure, reproducible code, honest caveats) and expect to defend every modeling choice.
Who takes this round: Quantitative Researcher candidates. See the full XTX Markets process and who takes each round.
How to prepare for the Take-Home / Technical Data Round
- Guard against multiple testing and overfitting explicitly — say how you'd control false discoveries when you try many features.
- Write clean, reproducible code. Treat it as work you'd hand a colleague: clear structure, sane defaults, numerically stable steps.

Common mistakes
- Validate, don't just fit. Show an out-of-sample / cross-validation story and a baseline before any fancy model. XTX cares about the diagnostics.
