Interview Questionnaire 

2 Questions

  • Q1. What is inheritance
  • Ans. 

    Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.

    • Inheritance allows for code reuse and promotes modularity.

    • The existing class is called the parent or base class, while the new class is called the child or derived class.

    • The child class inherits all the properties and methods of the parent class, and can also add new properties and method...

  • Answered by AI
  • Q2. Inheritance is process through which child class inherits properties of base class
  • Ans. 

    Inheritance is a mechanism in object-oriented programming where a subclass acquires the properties and behaviors of its parent class.

    • Inheritance allows for code reuse and promotes a hierarchical organization of code.

    • The child class can override or extend the properties and behaviors inherited from the parent class.

    • Inheritance can be single, multiple, or multilevel depending on the number of parent classes involved.

Round 1 - Coding Test 

(3 Questions)

Round duration - 90 minutes
Round difficulty - Medium

Questions on aptitude, English, logical reasoning, C/C++ and 5 coding ques. (only pseudo code).

  • Q1. 

    Minimum Jumps Problem Statement

    Bob and his wife are in the famous 'Arcade' mall in the city of Berland. This mall has a unique way of moving between shops using trampolines. Each shop is laid out in a st...

  • Ans. 

    Find the minimum number of trampoline jumps Bob needs to make to reach the final shop, or return -1 if it's impossible.

    • Use Breadth First Search (BFS) algorithm to find the minimum number of jumps required.

    • Keep track of the visited shops to avoid revisiting them.

    • If a shop has an Arr value of 0, it is impossible to reach the final shop.

    • Return -1 if the final shop cannot be reached.

  • Q2. 

    Smallest Window Problem Statement

    Given two strings, S and X, your task is to find the smallest substring in S that contains all the characters present in X.

    Example:

    Input:
    S = "abdd", X = "bd"
    Outpu...
  • Ans. 

    Find the smallest substring in S that contains all characters in X.

    • Use a sliding window approach to find the smallest window in S containing all characters of X.

    • Maintain a hashmap to keep track of characters in X and their frequencies in the current window.

    • Slide the window to the right, updating the hashmap and shrinking the window until all characters in X are present.

    • Return the smallest window found.

    • Example: S = 'abd

    You need to determine all possible paths for a rat starting at position (0, 0) in a square maze to reach its destination at (N-1, N-1). The maze is represented as an N*N ma...

  • Ans. 

    Find all possible paths for a rat in a maze from start to destination.

    • Use backtracking to explore all possible paths in the maze.

    • Keep track of visited cells to avoid revisiting them.

    • Return paths in alphabetical order as a list of strings.

Round 2 - Face to Face 

(3 Questions)

Round duration - 60 minutes
Round difficulty - Easy

Questions based on OOPS were asked in this round.

  • Q1. What is a virtual function?
  • Ans. 

    A virtual function is a function in a base class that is declared using the keyword 'virtual' and can be overridden by a function with the same signature in a derived class.

    • Virtual functions allow for dynamic polymorphism in C++

    • They are used in inheritance to achieve runtime polymorphism

    • Virtual functions are declared in a base class and can be overridden in derived classes

    • They are called based on the type of object bei...

  • Answered by AI
  • Q2. What are the types of polymorphism in Object-Oriented Programming?
  • Ans. 

    Types of polymorphism in OOP include compile-time (method overloading) and runtime (method overriding) polymorphism.

    • Compile-time polymorphism is achieved through method overloading, where multiple methods have the same name but different parameters.

    • Runtime polymorphism is achieved through method overriding, where a subclass provides a specific implementation of a method that is already defined in its superclass.

    • Polymor...

  • Answered by AI
  • Q3. What is the difference between deep copy and shallow copy?
  • Ans. 

    Deep copy creates a new object and recursively copies all nested objects, while shallow copy creates a new object and copies only the references to nested objects.

    • Deep copy creates a new object and copies all nested objects, while shallow copy creates a new object and copies only the references to nested objects.

    • In deep copy, changes made to the original object do not affect the copied object, while in shallow copy, ch...

Interview Preparation Tips

Round: Test
Experience: 1. Rotate a matrix by 90 degrees clockwise.( He asked me have you heard of question.I said Yes.Then he asked me to code)2. Find vertical sum of nodes present in same vertical line in binary tree. ( He again asked me have you heard of question. I have heard it but didn’t remember the approach. It took some time and then I started telling my approach.He aasked me to write code and question regarding get sums from left to right , for which I made use of linked hashmap)
Overall It was very cool for me
Total Questions: 2

Round: Test
Experience: 1.Reverse K blocks of nodes in linked list.There are two interviewers this time, probably, guy was senior he was asking me question.He was very particular in coding. Checked every edge case.and asked me evrything.Initially I told the approach and then started coding.2.Find min in stack in O(1)Pretty straightforward written code.Again he checked all edge cases with my code.3. Then asked about counting sort and its code.4. And a simple question on array sorting.

Round: HR Interview
Experience: I thought this was last round as they have said like.She asked me about my strengths and challenges I faced.How I overcame through it1.Basic question on oops concepts.(runtime polymorphism).
2.Design tables for getting all employees under manager. I screwed it little bit.But some how I got answer which I was not satisfied as well.I was expecting result either yes/no.But they called me for another round of interview may be because of my expected salary which was high compared to my previous.

Round: Technical Interview
Experience: 1.Given “aaabbbccc” it should return “a3b3c3″ in place. Initially I explained brute force approach then he said array has 2n space.I was able to remember approach for quicksort and started explaining after which I grew confident on it.He was satisfied.Questions on time complexity of algo and space complexity discussions.2.Again a question on OOPs.This time I was completely wrong in answering it.I thought interview with yatra was closing for me.He was not satisified much with this.Luckily, there was another round with manager.

Round: Other Interview
Experience: 1.He asked me to find words which are having particular pattern.Then I said it was KMP algo. Can I explain it ?? I started explaining approach, may be he was busy with something, he asked me to write pseudo code.He left the room for 15 mins then he came back I had almost completed the code, which he was satisified.Some basic questions on spring ( my previous work was related to it). Then my expected salary and my position If I got selected in yatra were discussed.
