The Virtu Financial Onsite / Superday interview is stage 4 of 5 in the Virtu Financial interview process, after the Technical Phone. Format: Back-to-back rounds · opens with an IQ test. Opens with a ~30-60 min IQ/logic test (50-60 figure-pattern and number-sequence questions, some GRE vocab and mental math), then resume + mixed probability/combinatorics/brain-teaser rounds, and a final modeling-heavy round with a team lead / regional head (a common rejection point).

What the Onsite / Superday tests
Traders may also get an arithmetic/mental-math test.
QuantVault maps 13 practice problems to this round. By topic, the biggest groups are probability (4), brain teasers (3), combinatorics (2), expectation (2); by difficulty, 2 easy, 9 medium and 2 hard. 10 of them were reported by candidates who interviewed at Virtu Financial, most recently in Jul 2025.
- A full day with senior traders and team leads that includes an IQ-style logic test, multi-step probability and behavioural questions.
How to prepare for the Onsite / Superday
- Warm up on figure-pattern + number-sequence puzzles (MathCounts/AMC level) for the IQ test.
- Onsite probability classics: 25 horses, two chords cross, 100 sharks survivors, the drunkard's escape walk.
- The modeling final is where people get cut — structure an open-ended modeling answer (baseline → assumptions → refinement).
