Given n non-negative integers a1, a2, ..., an, where each represents a point at coordinate (i, ai). n vertical lines are drawn such that the two endpoints of line i are (i, ai) and (i, 0). Find two lines, which, together with x-axis forms a container, such that the container contains the most water. Note: You may not slant the container and n is at least 2.

Given an m x n board of characters and a list of strings words, return all words in words that can be found on the board. Each word must be constructed from letters of sequentially adjacent cells, where adjacent cells are horizontally or vertically neighboring. The same letter cell may not be used more than once in a word.

Design an algorithm or data structure to maximize the number of unique characters under specific constraints or within a given data set. (Details for this AI-enabled coding problem were not provided beyond the title.)

Design a system for a live leaderboard, similar to LeetCode's, which tracks user scores and ranks in real-time. Consider aspects like data ingestion, real-time updates, query performance, scalability, consistency, and fault tolerance.

Answer standard behavioral questions using the STAR (Situation, Task, Action, Result) method. These typically cover topics like conflict resolution, teamwork, leadership, failure, success, and handling challenges, assessing communication, problem-solving, and interpersonal skills.
