My Interview experience with Amazon for SDE 2 Role

Round 1: Problem Solving and LP's

1. Given an array of integers and a number x. FInd the minimum length of the subarray with a sum greater than the given value of x.
   Input array: {1,4,45,6,0,19}, x = 51, Output = 3

2. Given an array of strings words(without duplicate), return all the concatenated words in the given list of words. A concatenated word is basically a string which comprise entirely of at least two shorter words (not necessarily distinct) in the given array.

   Example 1:
   Input: words={"cat","cats","catsdogcats", "dog", "dogcatsdog", "hippopotamases","rat","ratcatdogcat"}
   Output: {"catsdogcats", "dogcatsdog", "ratcatdogcat"}
   Explanation: "catsdogcats" can be concatenated by "cats", "dog" and "cats";
   "dogcatsdog" can be concatenated by "dog", "cats" and "dog";
   "ratcatdogcat" can be concatenated by "rat", "cat", "dog" and "cat";

   No LP's was asked as the coding part took more time then expected.

   Verdict: Strong Hire
