Two Sum — Indices Summing to a Target

Company: J.P. Morgan

Role: Software Engineer

Category: Coding & Algorithms

Difficulty: medium

Interview Round: Onsite

Quick Answer: 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.
