Ubisoft Interview Experience | On-Campus 2021

• On-Campus Interview
• Role: R&D Intern + PPO
• Total Number of Round: 4 Rounds
• Difficulty Level: Medium

Round 1(Coding Round – 60 min): The first round consisted of 2 Coding Questions on the https://www.codility.com/ platform.

• The 1st Problem is for Coding and the 2nd question is to find errors and correct them.
• The first question was easy but the 2nd question was a bit tricky (we get a limited number of lines we can change in order to correct code. In my case I can only change 3 lines in the code).

Tips: Solve the questions with a calm mind. Don’t stress yourself during the test because you have to do 2 questions in 60 minutes. There is ample time to solve questions.

Round 2(Technical Round 1 – 60 min): The interviewer started with an Introduction from both sides and then immediately moved to the project I mentioned in my resume.

• Project based on Decentralization of library system (MERN stack). We discussed the project for around 15 min.
• Then he moved to CPP and OOP.
• Explain Basic Concepts of OOP.
• What are Polymorphism and its types?
• Write code for dynamic polymorphism with real-life examples.
• What is a copy constructor? And its syntax?
• Why do we write “const” and pass an object as a reference in the copy constructor? (https://www.geeksforgeeks.org/copy-constructor-in-cpp/)
• What is shallow copy and deep copy? Which copy constructor does what type of copy and in which condition? (prefer above link for answer)
• what will happen in code?
  
  C++

  #include <iostream>
  using namespace std;
  
  class Demo {
  public:
      Demo() {}
      Demo(const Demo& t)
      {
          cout << "Copy constructor called " << endl;
      }
  
      Demo& operator=(const Demo& t)
      {
          cout << "Assignment operator called " << endl;
          return *this;
      }
  };
  
  int main()
  {
      Demo t1, t2;
      t2 = t1;
      Demo t3 = t1;
  }
  Output

  Assignment operator called 
  Copy constructor called 

• Then Asked me to write a code for 1 simple program: Given a string as Input. output number of continuous similar characters.

  Input: “abccchddgdddhccaaa”
  Output:  
  c: 3
  d: 2
  d: 3
  c: 2
  a: 3

• Asked me, do you have any questions?

Round 3(Technical Round 2 – 45 min): Again Start with an introduction and discussion on 2-3 projects.

• What are constant variables?
• Can we initialize const variables in the constructor? Why?
• If we want a constructor to initialize const variables how can we do that? explain. (Ans – Initialization list)
• What is Singleton class? Write 1 example of a singleton class?
• What is an empty class? What is the size of an empty class?
• What is call by value, call by reference, call by address?
• Where can we use these calls? (continue with earlier question)
• What are pointers? What is the size of char pointer, integer pointer, class pointer?
• Asked me to write a program. https://leetcode.com/problems/max-consecutive-ones/ 
• Asked me, do you have any questions?

Round 4(HR Round – 20 min):

• Tell me something about yourself.
• Why do you want to join Ubisoft?
• Do you have any plans for higher studies?
• Do you have any Location constraints?
• Any questions?

After 2 days we got the result and I was shortlisted.
