After applying online, I quickly received the online assessment (OA) link, valid for one month. The OA consisted of three coding questions, with a time limit of 120 minutes. The difficulty was roughly equivalent to LeetCode's easy-medium level. The first question was a minimum swap problem: find the minimum number of swaps required to sort an array. The second question was an array manipulation problem: sum the differences between each element and its leftmost and next-to-left elements. The third question was a relatively basic dynamic programming problem: find the maximum sum of subsequences in an array, with the constraint that you cannot skip two or more consecutive numbers. Please give me some points!
