What the AIA Lab tests
A data-manipulation problem in numpy/torch with the Head of AI, a LeetCode BFS/DFS coding round, and a system-design round (a fully-automated parking-lot system). numpy array-operation fundamentals are quizzed in detail.
QuantVault maps 2 practice problems to this round. By topic, the biggest groups are coding (2); by difficulty, 1 easy, 1 medium and 0 hard. 1 of them were reported by candidates who interviewed at Bridgewater Associates, most recently in Mar 2026.
How to prepare for the AIA Lab
- Know numpy/torch array ops cold — broadcasting, reshaping, indexing, vectorization.
- Practice clean BFS/DFS — standard graph traversal under time pressure.
- Be a generalist — they want ML + coding + system-design depth, not a single specialty.
Final-week checklist
- Internalize the 'Principles' / radical-transparency culture (fit is graded heavily)
- Structured multi-angle case reasoning (revenue, profit, casino, allocation)
- Fast fair-value mental math for the order-book superday round
- SWE: SQL joins, sentence-boundary parsing, parking-lot system design
- AIA Lab: numpy/torch ops + BFS/DFS + system design
