Info Edge Interview Experience | (On-Campus)

Round 1: It was a written test which consisted of three sections-aptitude, technical(multiple choice questions) which included mainly data structures, sorting, searching, time complexities, programming-it had two questions

1) Given a matrix print its transpose

2) Given 5 lists of integers print distinct elements once for each list on a new line. You may refer similar article : Print distinct elements.

Round 2:technical interview

He asked me if i’m comfortable with mysql and later shifted to data structures

  1. Find the square root of a number upto 1 decimal place
  2. Given an array of 0’s and 1’s sort it

I told by using 2 variables we’ll maintain the count and later just overwrite the array, he asked me to solve it in one traversal of array, then i told him have two pointers one from starting and other from end and as soon as we find the first 1 from left and first 0 from right swap them, (similar to quick sort) and do like this until both the pointers meet

Round 3:technical interview

He asked me to find number of squares in an n x n square and asked algo for it. Similar article Number of squares on NxN chessboard using general formula.

Just try to focus in the interview, problems were easy, but a little tricky.
