Two Sum — Indices Summing to a Target
Company: J.P. Morgan
Role: Software Engineer
Category: Coding & Algorithms
Difficulty: medium
Interview Round: Onsite
Overview: This question evaluates a candidate's ability to design an efficient array-searching algorithm that maps values to indices under a target-sum constraint. It tests understanding of hash-based lookups versus brute-force pairwise comparison, a foundational data structures and algorithms topic in coding interviews. It is commonly used to assess time-complexity reasoning at an introductory to intermediate practical level.
