Maven-Style Assessment
One sitting in the reported shape of the online assessment Maven Securities sends for its trading spring week, summer internship and graduate programmes: 50 typed mental maths questions in 5 minutes, 30 number and letter sequences in 6 minutes, 18 five-option probability questions in 30 minutes where a wrong answer costs a point, and one quantity to estimate with an 80% confidence interval in 2 minutes. The questions are ours, not the real paper, and the counts and clocks are what candidates report, because Maven publishes none of them.

What the real one is reported to be
Maven's Emerging Talent page says you may sit one or more online assessments depending on the programme and business area, and names four: a numerical test of mental maths ability, which it suggests practising on Zetamac under timed conditions; a probability test, with the advice to use the full time limit; a HackerRank coding test for technology roles; and an Arctic Shores task-based assessment. It publishes one example question, an 8-sided die rolled until two 8s come up in a row and the expected number of rolls, with five options. It publishes no question counts, no clocks and no marking scheme.
Candidates for the trading programmes describe three timed tests: mental maths at about 50 questions in 5 minutes with no calculator or paper, number and letter sequences at about 30 in 6 minutes, and multiple choice probability at about 18 in 30 minutes on expected value, combinatorics, conditional probability and classic puzzles, with several reports of minus one for a wrong answer and nothing for a blank. Reports from August 2026 describe a newer version with typed answers, a shorter probability block of about 20 questions in 10 minutes, and an added estimation question: one unknown quantity, two minutes, an 80% confidence interval, and your reasoning explained aloud to the proctoring camera. The older format was still being reported in late 2025, so prepare for both.
How it is scored here
A point a question, 99 in all. Nothing is deducted on the typed sections, because a typed test has nothing to guess from. On the probability section a wrong pick costs a point and a skip costs nothing, which is what most accounts of the real one say and the habit the format rewards; a section that goes below zero counts as zero. The estimation question scores when the true value sits inside your interval and the upper bound is at most 10 times the lower, so an interval that captures everything scores nothing. Each section runs on its own clock, with a brief and a 30 second countdown before it, and the whole sitting is 45:00 at most.
Where we had to choose
The accounts disagree on whether the maths and sequences are typed or multiple choice. The 2026 reports say typed, so that is what runs here; the older click to advance version is the 50 in 5 mode of Mental Maths. The probability section keeps the five-option shape of Maven's own example and the counts most accounts give rather than the shorter 2026 block, because the longer paper covers the shorter one. The confidence level on the estimation question is the reported 80%, and the width limit is ours: Maven publishes nothing about how an interval is judged. Letter sequences read letters as positions in the alphabet and never wrap past Z, because a wrapped sequence has two readings.
The parts that are not here
The Arctic Shores stage, which some cohorts sit before the numerical tests and some after, is Arctic Shores-Style Tasks. The HackerRank test for technology roles is a coding round, and nothing here runs one. After the online tests the reported process is a recorded video interview on motivation, an HR and technical interview with brainteasers and market making games, and a final round of one to four hours with senior traders: Quant Interview and Make a Market cover those.
The sections on their own
What is known about Maven's assessment, with the sources, is on the Maven Securities firm page. For one section at a time: Mental Maths for the arithmetic, Sequences for the number patterns, Probability for the families the middle section draws on, and Fermi Estimation for the intervals. Every ranked game feeds the overall leaderboard.
