What the test is like

Hudson River Trading assessment

Built by CodeSignal

Format
Not a maths test. Algorithmic coding problems in Python or C++, auto graded on hidden test cases, with trading flavoured problem statements over what is really an engineering exercise.
Timing
Reported at 3 to 4 problems somewhere between 70 and 150 minutes depending on the role. Auto grading means partial credit comes from tests passed, so there is no penalty scheme to manage.
What is uncertain
The time range is wide because different roles sit different papers, and none of it comes from HRT directly.
How to practise
Nothing here runs this format. It is an engineering round, so practise on a coding platform with hidden test cases, and rehearse the edge cases graders always include: the empty input, the single element, the case where nothing works.

What students report this cycle

No debriefs about Hudson River Trading's test yet this cycle. Students who track an application here can say what they sat afterwards; once a firm has three, the counts show here.
