Amazon Interview | Set 106 (On Campus for Internship)ReadDiscussCoursesPracticeImprove Article ImproveSave Article SaveLike Article LikeAmazon came to our campus recently for placements and internships. I attended for internship and i am sharing my experience here.First Round: Online:20 MCQs based on basic aptitude,OS,C programming and data structures.2 coding questions:Consider a coordinate system consisting of n coordinates from (x1,y1)…..(xn,yn)Also there are two values ymin and ymax given to you. You have to return min(D) where D is x^2 + y^2 for all y lying between ymin and ymax inclusive. If there is no such y then return -1.Given a number n and a number k. You have to find the next bigger number from n which is obtained after exaclty k swaps.Eg: Take n=43592169 and k=5 1st swap: 43952169 2nd swap: 49352169 3rd swap: 94352169 4th swap: 94532169 5th swap: 95432169 :- final number.First Interview:Check if a linked list is palindrome or not.Given an array of n integers(positive or negative). Find the maximum sum of subsequence of the array and also total number such arrays possible having the maximum sum.Second Interview(Final):A linked list consists of two pointers: a next pointer and a child pointer. We have to make the linked list linear i.e. making all the child pointers NULL.eg: 1->2->3->4 | | 5->6 8 | 7 answer would be: 1->2->3->4->5->6->8->7.Given a distance n. A person standing at position 0 has to reach n. He can either take 1 step or 2 steps at a time. In how many ways he can reach there.Finally some definitions from OOPS, OS and basic data structures.I was finally hired for the Internship at Amazon. I would like to thanks Geeks for Geeks which helped me a lot in my preparation.If you like GeeksforGeeks and would like to contribute, you can also write an article and mail your article to contribute@geeksforgeeks.org.
