The assessment consisted of three parts and took approximately four hours in total.

• The first was a LeetCode-style coding challenge focused on applying the prefix sum technique.
• The second involved being given a full codebase — both frontend and backend — and tasked with identifying and fixing bugs such as broken search/filter functionality and incorrect URL redirects; an AI tool was available throughout, though it only provided guidance rather than direct solutions.
• The third was a behavioral assessment where I was presented with realistic workplace scenarios, including sample work emails, and asked to evaluate hypothetical responses by rating their appropriateness and explaining my reasoning.

Given an array of integers, use the prefix sum technique to solve [specific problem type, e.g. range sum queries / subarray sum].

You are given a full web application codebase (frontend and backend). Identify and fix bugs including broken search/filter functionality and incorrect URL routing, using an AI assistant for guidance only.
