There were some technical questions MCQ based. Then there were 2 coding questions,i don't remember the questions exactly ,but one was a medium level array manipulation question and the other was medium level string manipulation question.

The round was of 1 hour .SHL platform conducts the Aptitude and Verbal Reasoning. It had two sections, first was a numerical ability which had questions mostly on Data interpretation (Tables, Bar graphs, and Pie charts). Calculators were allowed however you had to be extremely fast in your calculations as the timing constraints were very strict and you could not go back to the previous question. The second section was verbal reasoning which was mostly reading comprehension based. I was preparing for GMAT so I was all brushed up. I would recommend to go through the SHL sample papers to become familiar with the format of aptitude and Verbal reasoning questions.

[ON CAMPUS] It was about 50 MCQs + 2 Coding Problems

The first section of MCQs were based fundamental CS concepts like OOP, Computer Networks, DBMS, OS etc. The second section had code snippets and questions included to predict the output,
find the error statement, fill in the blanks etc.

Each candidate received different set of questions. Most of the questions were based on arrays, strings, stack and queue. I was asked the following two questions: Minimum Platform (GFG) and Valid Parentheses (LeetCode).

This round had 2 sections. First section had questions on data explanatory, data visualization, data interpretation, math, statistics etc. Second section was about English. Overall the questions were slightly difficult. This round was challenging because the time allotted to each section was very less.

This round was immediately followed by an SHL aptitude test which was basically a quick limited time check of your verbal ability and maths because many questions were to be done in 1 hour.

Q1. 
Matrix Transformation Problem Statement
Given a 2-dimensional matrix of size NxN containing 0s and 1s, the task is to modify the matrix such that, if an element is 1, set its entire row and column to 1. I...read more
Ans. 
Modify a matrix by setting entire row and column to 1 if an element is 1, then count the number of 1s.
• Iterate through the matrix to find elements with value 1

• Use two arrays to keep track of rows and columns to be modified

• Update the matrix by setting entire row and column to 1 if an element is 1

• Count the number of 1s in the modified matrix

Ans. 
Euler's Totient Function calculates count of integers coprime to N between 1 and N.
• Implement Euler's Totient Function to calculate count of coprime integers to N.

• Use the formula: phi(N) = N * (1 - 1/p1) * (1 - 1/p2) * ... * (1 - 1/pk) where p1, p2, ..., pk are prime factors of N.

• Example: For N = 9, phi(9) = 9 * (1 - 1/3) = 6.
