Two Sigma

Two Sigma Quant Research Online Assessment

The long HackerRank sitting candidates describe for Two Sigma: three questions in about three hours under one block timer, normally one algorithmic and two data-analysis. Libraries are allowed on the real thing, which moves the bar from recalling an algorithm to implementing a regression, an interpolation or a rolling statistic that is correct at the edges and fast enough at size.

Format

• 1 section · 3 items · about 180 minutes
• No negative marking - answer everything.
• Every sitting is generated fresh - a retake is a new paper.

Sections

• Coding and data analysis - 3 items, 180 minutes, no negative marking. Three problems, 180 minutes, one clock across all three. Least squares, interpolation, rolling statistics, quantiles, resampling and pandas-style column work, implemented from scratch and graded on hidden tests plus a performance gate.
