  • Q1. What is aingleton and how it ia thread safe?
  • Ans. 

    Singleton is a design pattern that restricts the instantiation of a class to one object and provides a global point of access.

    • Singleton ensures that only one instance of a class is created and provides a way to access it globally.

    • It is thread-safe because the instance is created only once and accessed through a synchronized method or block.

    • Singleton can be implemented using different approaches such as eager initializa...

  • Q2. What ia base class of class in c#?
  • Ans. 

    Object class is the base class of all classes in C#.

    • Object class provides basic functionalities like ToString(), GetHashCode(), and Equals() to all classes.

    • Object class is defined in System namespace.

    • Example: class MyClass : Object { }

  • Q3. Access modifiers in c#
  • Ans. 

    Access modifiers in C# control the visibility and accessibility of class members.

    • Public: accessible from anywhere

    • Private: accessible only within the class

    • Protected: accessible within the class and derived classes

    • Internal: accessible within the same assembly

    • Protected Internal: accessible within the same assembly and derived classes

    • Example: public int age; private string name;

    • Example: protected void DoSomething(); intern

  • Q4. Default aceess modifiers?
  • Ans. 

    Default access modifiers are public, protected, and private.

    • Public: accessible from anywhere

Technical Interview round with questions on C#, Design patterns, OOPS etc.

  • Q1. What is a base class?
  • Ans. 

    A base class is a class that is used as a starting point for creating other classes. It can be inherited by other classes.

    • Base class provides common attributes and methods that can be inherited by other classes

    • Derived classes can extend or override the functionality of the base class

    • Example: Animal can be a base class with attributes like name and methods like eat, sleep

  • Answered by AI
  • Q2. What is a singleton design pattern?
  • Ans. 

    Singleton design pattern ensures a class has only one instance and provides a global point of access to it.

    • Used to restrict the instantiation of a class to one object

    • Commonly used in logging, caching, thread pools, database connections

    • Implemented by creating a static instance of the class and a private constructor to prevent external instantiation

  • Answered by AI
  • Q3. What are the different access modifiers in C#?
  • Ans. 

    Access modifiers in C# control the visibility and accessibility of classes, methods, and other members.

    • Public - accessible from any other class or assembly

    • Protected - accessible within the same class or derived classes

    • Internal - accessible within the same assembly

    • Protected Internal - accessible within the same assembly or derived classes

  • Answered by AI
  • Q4. What is the default access modifier in C#?
  • Ans. 

    The default access modifier in C# is 'private'.

    • Default access modifier is applied if no access modifier is specified for a class member

  • Q1. Boundary traversal of a tree
  • Ans. 

    Boundary traversal of a tree is the process of visiting the nodes on the boundary of a tree in a specific order.

    • The boundary traversal can be done in three steps: left boundary, leaf nodes, and right boundary.

    • For the left boundary, start from the root and traverse down the left side of the tree until reaching a leaf node.

    • For the leaf nodes, perform an inorder traversal to visit all the leaf nodes of the tree.

  • Q2. Find the nearest greater value of a given value in a BST
  • Ans. 

    Find the nearest greater value of a given value in a Binary Search Tree (BST).

    • Start from the root node and compare the given value with the current node's value.

    • If the given value is less than the current node's value, move to the left subtree.

    • If the given value is greater than the current node's value, move to the right subtree.

    • Keep track of the closest greater value encountered while traversing the tree.

  • Ans. 

    Given an infinite staircase with a broken kth step, find the maximum height we can reach in n rounds of jumping i steps.

    • We can start by jumping the maximum number of steps in each round until we reach the broken step.

    • After reaching the broken step, we can discard the i steps that would land us on the broken step and jump the remaining steps.

    • We can continue this pattern until we reach the maximum height we can reach wit

Interview Preparation Tips

Round: Test
Experience: there were 20 MCQ which were on ds , networks and basic coding followed by 2 coding questions.
1) print all the distinct substrings of a given string in lexicographical order
2) find the max i-j value in the given array of 0's and 1's such that there are equal number of zeros and ones, where i is the starting index and j is the ending index of the array.
Tips: make sure that you pass atleast half the test cases for both the question.
Duration: 90 minutes
Total Questions: 22

Round: Technical Interview
Experience: 1) i printed left view then leaves and right view using three level order traversals . he asked me to use one traversal only, then i told him the approach and wrote the working code.
2) told him the approach and coded it.
Tips: look at corner cases properly. the interviewers were friendly, so i felt relaxed.

Round: Technical Interview
Experience: 1) i told him a recursive O(2^n) solution, optimised it to O(n^2). he told me to optimise further. Then i finally came up with O(n) solution after 5 min and he was satisfied . i coded it. he was satisfied finally :D .
2) came up with the approach immediately and coded it. he was satisfied.
Tips: he was very particular about corner cases and he checked the code througly tested it on some cases to ensure it was working.

General Tips: be cool. interviewers were friendly. tell them what you are thinking and be clear with the question before answering to avoid wasteage of time.
Skill Tips: solve problems from codechef, spoj and codeforces. solve interview questions from geeksforgeeks and careercup.
Skills: the way you think, coding skills and knowledge on data structures.
Duration: 3
College Name: IIT Roorkee
Motivation: some good seniors got intern, so i was inspired.
Funny Moments: on the interview day a person came into the conference room to call me for interview, i didnt thought he was interviewer. he was very simple, but intelligent and at last i felt like asking him to ask me one more coding question as it was fun solving questions infront of him, but i didnt do that as i was frightened if i would not be able to answer it would be a negative remark :P .
