Arcesium
Arcesium is a global financial technology firm (spun off from D.E. Shaw) providing post-trade data management and analytics solutions for hedge funds, asset managers, and banks. Their India engineering center in Hyderabad is a key engineering hub. Arcesium interviews are highly rigorous — they deeply test OOPs (especially vptr/vtable, SOLID principles), DBMS (normalization 1NF–5NF, ACID properties), and DSA (trees, graphs, DP, arrays). They expect optimized, O(1) space solutions and thorough dry runs.
