Written Round: This Round was pen and paper round consisted of 45 questions out of which only 2-3 are aptitude and rest are from DS, OS, C, C++, Networking, DBMS. Questions were standard so you should well aware of these concepts though most of the questions were from geeksforgeeks. You need to correct about 30 – 35 question to clear this round. Total 227 students appeared out of which 82 students are shortlisted Coding round(9 Were shortlisted): This round consists of 4 questions that has to be solved in 2 hours. 1.Given an array find whether it can be divided into two parts such that both parts sum is equal. 2. https://www.geeksforgeeks.org/find-the-smallest-window-in-a-string-containing-all-characters-of-another-string/ 3. Print the prime number between some given range 4. Given a sorted array of numbers, find the total number of elements within a range(inclusive). Please do mention the time and space complexity in the comments otherwise your solution will not be accepted. Ex a = [1,2, 4,5, 8,10,12] range = [3,6] Output:- 4 5 Restriction:- You can’t use STL Round 1( 6 were shotlisted :: Duration 2 hours) 1. You are given an array of integers and four operators + , * , ( , ) and using these four operator you have to find the maximum sum that you can make Example: array elements are {1,2,3) Lets examine two scenario 1*2*3 and (1+2)*3 so second is giving 9 and first is giving 6 so answer should be 9. 2.You are given a integer n find how many ways you can make palindrome number consisting of n digits and print it also you are not supposed to use any array or character array means you can only use recursion. Example : n = 2 then answer would be 11,22,33,………………………. 3. https://www.geeksforgeeks.org/find-number-of-islands/ 4. Project discussion thoroughly. Round 2(Duration 1 hours approx.) 1. Given a matrix with some empty cell and some cell having bomb and you are at (0,0) and you have to reach to a given location say (destx, desty) find whether there is a possible path of not if Yes print the minimum distance you can only go through empty cell. 2. https://www.geeksforgeeks.org/given-sorted-dictionary-find-precedence-characters/ 3. Given an integer you have to find the minimum length of factor such that none of the factor is perfectly divisible by any perfect square. Input#1: n = 180 Output#1 : 6 * 30 having length 2 Input#2: n = 166320 Output#2: 2x6x6x2310 having length 4 Note : Firstly find prime factor and then think 4. Topological sorting(Kahn’s algorithm discussion) 5. Small discussion on project Round 3(Duration : 45 minutes) This was skype round and taken by founder and roughly about 5 minute project discussion and about 30 minute OS question In OS: How OS execute some program. Thrashing , reason of thrashing and how to resolve it. Deadlock and starvation thoroughly discussion how to eliminate. Demand paging Page replacement techniques Some basic HR questions
