Round: Test
Experience: Totally 5 questions. Duration is 3 hours. But they provide 30 mints extra. Use language for solving problem but they prefer C, if u solve the problem in C then u made get good comments. Logic , coding style, memory management are important. I solve 1 problem in C and remaining problems in Java. I use OOPs in better way so I add me additional points. If u don’t have time to solve the problem, just explain the logic.Questions 1: use best data structure to store numbers which are given at any point in time. U need to find out the median for those no.Question 2: find the 1st non-repeated letter from array of Strings.BH BH FC AG HG HC – ans FQuestion 3: divide the given array into 2 part such that average of part should be same.Question 4: replace the no by least max no of right side( if no then substitute -1)Input:    43 3 91 95 25 32 80Output:  80 25 95 -1 32 -1 -1Question 5: (LRU. Least recently used ) data structure for LRU such that it hold Key and Value with some conditions to implement LRU(similar to Map in Java Collections).(I only complete 4 qus and I explain only logic for Q3)

Round: HR Interview

Round: Problem Statement
Experience: I created HashMap using Java. But others used BST(but most optimized data structure is B-tree or B+ tree). I explained HashMap, B+ tree and my logic for spell check and suggestion and I analyzed the question and asked many questions and suggestions for optimizing the solution. They were impressed.
