How long is the Squarepoint HackerRank Screen practice sitting?

Outcry’s mock has 12 items across 1 section, with 60 minutes of section time. Those figures describe this mock; see the source check for any published format elements.

Will Squarepoint HackerRank Screen use the same questions every time?

Outcry generates questions from its own banks. Counts and rules remain fixed; the selected problem types or numeric parameters change. Some archetypes may recur across attempts.

Squarepoint HackerRank Screen - Timed Practice

Squarepoint-focused statistics and coding practice, including a connected six-part dynamic-programming exercise. Outcry combines these skills in a 60-minute mock; this exact combined live assessment is unverified.

HackerRank screen - 12 items, 60 minutes, no negative marking. 12 items in 60 minutes. Four short statistics questions, two coding problems, then one question in six parts that ends in code. You may move between questions.

What this practice sitting covers

1 section, 12 items and 60 minutes of section time. Each section uses its own clock. Questions are generated from Outcry’s own banks; repeat attempts can share problem types with different selections or parameters.

How this mock is marked

Marking on HackerRank screen: +1 correct, 0 wrong, 0 for a skip. Any item-specific mark weight is shown on the question.

In this mock you can return to earlier questions within a section. Once a section ends, it is submitted.

Scores measure performance on these exercises. They are not a firm’s pass threshold or a prediction of an interview or offer.

Public sources and practice adaptations

Squarepoint’s early-career material describes its recruitment process but does not verify this precise 12-item, 60-minute combined paper.

The statistics tasks, coding tasks and six-part dynamic-programming exercise are combined by Outcry. Reports of different roles are not evidence that one candidate receives all of them.

Section by section, with a worked example

Every example below is generated by Outcry, drawn from the same generator that section runs during the timed sitting. None of it is Squarepoint's own material.

A. HackerRank screen

12 items in 60 minutes. Four short statistics questions, two coding problems, then one question in six parts that ends in code. You may move between questions.

In this Outcry section: 12 items in 60 minutes, averaging 300 seconds per item. Wrong answers receive no marks and carry no deduction. Unanswered items score zero. Correct-answer weights are shown on the questions. These are the mock’s rules.

Example 1

X and Y are independent, with standard deviations 17 and 30. What is the correlation between X and X + Y?

Answer 0.49301257198088033

Cov(X, X+Y) = Var(X) = 289, because X and Y are independent. SD(X+Y) = sqrt(289 + 900) = 34.482. So the correlation is 289 / (17 x 34.482) = 0.493. Adding independent noise to a series never makes the correlation zero, only smaller.

Example 2

x      12   22    7   18   23    5   17

What is the sample variance of the series above? Use the n-1 denominator.

Answer 49.8095238095238

The mean is 14.86. Squared deviations: 8.16 + 51.02 + 61.73 + 9.88 + 66.31 + 97.16 + 4.59 = 298.86. Divided by n-1 = 6 that is 49.81. The n denominator would give 42.69.

Example 3

Cov(X, Y) = 11. What is Cov(2X, 2Y + 2)?

Answer 44

Covariance is bilinear and a constant shift drops out: Cov(2X, 2Y + c) = 2 x 2 x Cov(X, Y) = 44. The added constant has no variance, so it cannot covary with anything.
