Calsoft Interview Experience | Set 1 (On-Campus)

Interview Experience of Calsoft Pune:-

First of all they gave PPT

After that there was an online Exam that was pure coding exam. There were three questions :
It was 2 hours exam.
Questions were fairly easy

Q1: Two strings are given S1 and S2 , replace all character in S1 with ‘+’ those are not there in string S2.
         example S1 = MOHIT and S2 = ROHIT, answer = +OHIT.

Q2: An integer array is given, we have to tell in which case it lies, cases are:-
         Case 1. array[5] = {4, 5, 6, 7, 8} ie series of natural number.
         Case 2. array[5] = {2, 3, 5, 8, 13} ie fibonacci series.
         case 3: array[5] = {9, 16, 25, 36, 49} ie square of natural number’s.

        example: given input array[7] = {10, 11, 12, 13, 14, 15, 16}, ans = case 1.
                 given input array[5] = {1, 1, 2, 3, 5}, ans = case 2.
                 given input array[5] = {1, 4, 9, 16, 25}, ans = case 3.

Q3. Given an input array and a integer n, we have two tell in how many ways we can get number n by summing the numbers of given array, we can use a number only once.
        example: array[5] = {1,3,7,9,10,11} and n = 12 then
        possible cases are 1+11, 9+3. so ans = 2.

I did all the questions and got first name in list.
After this exam they shortlisted 12 candidates for PI, I was.

They called me for PI, Some of the questions they asked were:-
