Show HN: AI 기반 기술 인터뷰 준비 도구를 만들었습니다.

An AI interviewer that speaks, listens, pushes back, and scores you — exactly like a real senior engineer would. Given an array of integers nums and an integer target , return indices of the two numbers such that they add up to target . You may assume that each input would have exactly one solution, and you may not use the same element twice. Example 1 Input: nums = [2,7,11,15], target = 9 Output: [0,1] Because nums[0] + nums[1] == 9 Constraints Time O(n) Space O(n) Voice AI Interviewer Alex isn't a form you fill out. It's a real-time voice conversation — asking follow-ups, calling out dead ends, and granting hints when you're stuck. The exact pressure of a real interview, available 24/7.
