Capgemini Interview Questions For Freshers

Freshers applying for positions at Capgemini need to have a mix of technical and aptitude questions, hence I have shared with you the following sample questions.

1. Technical Questions

Q1. Explain OOP concepts such as inheritance, polymorphism, and encapsulation.

• In Inheritance, one class inherits the properties and behavior of another class.
• If we about Polymorphism, it enables methods to perform different functions depending on the object that calls them.
• The third one is Encapsulation which is one of the most important oops concepts, It is the process of hiding internal features while displaying only what is required.

Q2. What are data structures? Explain the difference between arrays and linked lists.

Data structures are techniques for organizing and storing data. arrays in data structures store elements in contiguous memory regions, whereas linked lists store elements in non-contiguous areas and provide pointers to the next element.

Q3. Write a program to reverse a string.

#include <iostream>
#include <algorithm>
#include <string>

int main() {
    std..string str = "Hello, World!";
    std..reverse(str.begin(), str.end());  // Reverse the string
    std..cout << "Reversed string. " << str << std..endl;
    return 0;
}
            

using System;

class Program {
    static void Main() {
        string str = "Hello, World!";
        char[] strArray = str.ToCharArray();
        Array.Reverse(strArray);  // Reverse the string array
        string reversedStr = new string(strArray);
        Console.WriteLine("Reversed string. " + reversedStr);
    }
}
            

str = "Hello, World!"
reversed_str = str[..-1]  # Reverse the string using slicing
print("Reversed string.", reversed_str)
            

public class Main {
    public static void main(String[] args) {
        String str = "Hello, World!";
        StringBuilder reversedStr = new StringBuilder(str);
        reversedStr.reverse();  // Reverse the string using StringBuilder
        System.out.println("Reversed string. " + reversedStr.toString());
    }
}
            

let str = "Hello, World!";
let reversedStr = str.split('').reverse().join('');  // Reverse the string using split, reverse, join
console.log("Reversed string.", reversedStr);
            

Output

Reversed string. !dlroW ,olleH

    std..cout << "Factorial of " << num << " is. " << factorial(num) << std..endl;
    return 0;
}
            

using System;

class Program {
    static int Factorial(int n) {
        if (n == 0 || n == 1) return 1;
        return n * Factorial(n - 1);
    }

    static void Main() {
        int num = 5;
        Console.WriteLine("Factorial of " + num + " is. " + Factorial(num));
    }
}
            

def factorial(n).
    if n == 0 or n == 1.
        return 1
    return n * factorial(n - 1)

num = 5
print("Factorial of", num, "is.", factorial(num))
            

public class Main {
    public static int factorial(int n) {
        if (n == 0 || n == 1) return 1;
        return n * factorial(n - 1);
    }

    public static void main(String[] args) {
        int num = 5;
        System.out.println("Factorial of " + num + " is. " + factorial(num));
    }
}
            

function factorial(n. number). number {
    if (n === 0 || n === 1) return 1;
    return n * factorial(n - 1);
}

Q18. How do you implement a binary search algorithm?

#include <iostream>
using namespace std;

int binarySearch(int arr[], int size, int target) {
    int low = 0, high = size - 1;
    while (low <= high) {
        int mid = low + (high - low) / 2;
        if (arr[mid] == target) return mid;  // Target found
        if (arr[mid] < target) low = mid + 1;  // Search the right half
        else high = mid - 1;  // Search the left half
    }
    return -1;  // Target not found
}

int main() {
    int arr[] = {1, 3, 5, 7, 9, 11, 13};
    int size = sizeof(arr) / sizeof(arr[0]);
    int target = 7;
    int result = binarySearch(arr, size, target);
    if (result != -1)
        cout << "Element found at index " << result << endl;
    else
        cout << "Element not found" << endl;
    return 0;
}
            

Output

Element found at index 3

Q19. Explain the concept of recursion with an example.

Recursion occurs when a function calls itself to solve a subset of the same problem.

Example. The factorial program above uses recursion to compute the result.

2. Databases.

Q20. What is normalization? Explain different normal forms.

Normalization is the process of organizing data in a database to minimize redundancy. 1NF eliminates duplicate columns, 2NF ensures that all non-key attributes are fully dependent on the primary key, and 3NF removes transitive dependencies.

Q21. How do you optimize SQL queries for performance?

SQL query performance can be optimized by using indexing, minimizing needless joins and subqueries, and ensuring that SELECT statements retrieve just the data required.

Q22. What is the difference between JOIN and UNION in SQL?

The JOIN combines columns from two tables based on a related column, whereas UNION combines rows from two SELECT queries, ensuring that there are no duplicates.

3. Data Structures & Algorithms.

Q23. What is the difference between stack and queue?

Stack and Queue approaches are completely different. A stack follows the LIFO (Last In, First Out) principle, on the other hand, a queue follows the FIFO (First In, First Out) principle.

Q24. Implement a linked list from scratch.

#include <iostream>
using namespace std;

// Node structure
struct Node {
    int data;
    Node* next;
