Problem Overview

One report, from a two-round ML/Infra Engineer loop in early 2026. Round 1 is this coding exercise; the candidate describes it as testing distributed-systems intuition plus NumPy basics. You are handed incomplete starter code and asked to complete two parallel strategies for matrix multiplication. Both must return the same matrix…
