Quantitative Research Analyst Interview Questions

815 quantitative research analyst interview questions shared by candidates

Signed an NDA, but most questions were very open ended and required “practical solutions”, although some coding problems and puzzles/brainteasers obviously had right/wrong answers. My feeling is that they really try to make sure you’re a cultural fit to TS collaborative culture.

Problem Analysis: A k-star consists of a center node and up to k arms (edges to other nodes) We need to find the k-star with maximum sum of all its nodes For each potential center, we choose the best neighbors (up to k) to maximize sum Algorithm: Build an adjacency list from the edges For each node as a potential center: Get all its neighbors Sort neighbors by their values (descending) Select up to k best neighbors Calculate sum: center + selected neighbors Return the maximum sum found
