Plan for timed probability assessment | Optiver Interview Question

Quick Overview

This question evaluates rapid probabilistic and statistical reasoning, time management and problem prioritization under strict timing, along with the ability to adapt approaches based on scoring rules and calculator restrictions, and it is classified in the Statistics & Math domain.

Timed Probability/Statistics Assessment Strategy (30 Questions, Strict Time Limit)

Prompt

You are taking a timed online assessment with 30 probability and statistics questions under strict time pressure (similar to Optiver's "Beat the Odds"). Describe your approach:

How would you manage time across the assessment?
How would you choose the order of problems to maximize score?
How would you verify answers under pressure?
Which probability/statistics techniques would you prioritize and why?

Assumptions

30 multiple-choice questions with a fixed total time T.
Scoring may or may not include penalties for wrong answers (state how you adapt in each case).
Calculators may be restricted; mental math efficiency matters.
