Overview
Maven Securities' numerical test is one online test in timed sections: probability, speed maths and sequences, then a confidence-interval estimate as the last question. This test runs it as candidates reported it for the 2027 cycle, each section on its own clock. The directions ban pen and paper, a calculator and any other help for every section. Questions come one at a time and there is no going back. Each section ends when its last question is answered or its time runs out, and you start the next one yourself, so you can take a short break. To work on one part, pick a section on its own: it runs with the same clock and rules.
Game Phases
1
Probability
20 questions in 10 minutes, multiple choice. At about 30 seconds a question there is no time to work problems out, so you need to recognise standard problems and know their answers: skip a question you cannot place quickly.
2
Speed Maths
50 questions in 5 minutes: 4-digit additions and subtractions, 2-digit multiplications, percentages and a few divisions. Type each answer and press Enter. There is no skipping.
3
Sequences
30 basic number and letter sequences in 6 minutes, multiple choice: steady steps, doubling, squares, primes, letter patterns. Pick the term that comes next.
4
Confidence Interval
The last question: estimate a quantity, such as the height of a mountain or the number of Airbnb listings worldwide, with a lower and an upper bound. Candidates have not reported the confidence level, so here you give a range you are 90% sure holds the true value. Type 2.5k, 40m or 1.2bn for thousands, millions or billions.

Scoring
+1
Correct answer
Each correct answer adds one point, in every section. A confidence interval is correct when the true value lies inside it and the upper bound is at most 10 times the lower bound: a range that holds anything does not count. Some quantities have a looked-up value; the others are estimation questions, scored against our best estimate.
-1
Wrong multiple-choice answer
A wrong answer in probability or sequences costs a point, so skip when you are not sure.
0
Wrong speed maths answer or interval, skipped or not reached
A wrong speed maths answer or confidence interval costs nothing, and neither does a skipped question or one the clock did not let you reach.
Your score is the sections added up: correct minus wrong answers in the multiple-choice sections, plus correct speed maths answers and a correct interval. The maximum is 101. The results show each section's score, and the review lists every question with the correct answer, the full solution for the probability questions, and for the interval the sources of the value or a worked estimate.
