Leetcode coding question and some Machine learning system design. The problem on LeetCode is the Max Area of Island problem. The Max Area of Island problem is a common graph theory problem and a classic question on LeetCode. In this problem, we are given a matrix consisting of 0's and 1's, where 1 represents land and 0 represents water. An island is defined as a series of adjacent land cells (horizontal or vertical). We need to find the island with the maximum area, i.e., the island that contains the most land cells, and return its area. One common approach to solving this problem is to use depth-first search (DFS) or breadth-first search (BFS). Specifically, we can start the search from each land cell in the matrix and record the current island's size during the search. Finally, we can compare the sizes of all islands and return the one with the maximum area.

From the beginning since I got the HR screening call it didn't look like they wanted to hire me anyways but still scheduled the interview. After the HR screening call they scheduled the interview but the interviewer didn't show up for the call, so they rescheduled it to next week. Only one person from TuSimple showed up and started the interview. It looked like he wanted me to fail the interview and not the other way around.
