Round difficulty - Medium
The first round was scheduled in the evening time.
First of all interviewer introduced himself and after my introduction
He directly shoot first DSA question. The question was easy but conceptual. I have solved some question with same concept and he ask me to share the screen and code in online compiler. Finally I was able to get correct output with all the use cases and I was like "Half work done!"
Then he asked me very core concepts of JavaScript along with that Some Output based questions.
Then finally he asked me theory questions on React along with my experience in React.
The interviewer was very helpful as well as polite. I don't think if he will not help me during interview I could crack the interview
Ninja is relocating to a place called NinjaGram, and for school admission, he is required to identify if a given sentence is a pangram. Your task is to assist Ninja in determini...
Yes, the sentence is a pangram if it includes every letter of the English alphabet at least once.
Check if the sentence contains all 26 letters of the English alphabet.
Convert the sentence to lowercase to simplify the checking process.
Use a set to keep track of the letters present in the sentence.
Iterate through the sentence and add each unique letter to the set.
After iterating, check if the set contains all 26 letters.
Tip 1 : Code at least a single problem on your favourite coding platform with proper understanding of concept.
Tip 2 : Work on your resume, specifically try to grab some technical achievements(Hackathons, GSoc, etc) along with your degree which can stand out you from other candidates.
Tip 3 : Ask your friend for some mock interviews which can help you to excel in interview.
Tip 1 : Project description should contain maximum keywords mentioned in Job Description. Success Matrix of project will give you an edge in the interview.
Tip 2 : Resume should be one page along with some clickable GitHub and Achievments links if possible.

I applied via Indeed and was interviewed in Jul 2024. There were 2 interview rounds.
Classes, oops, array, constructor
A copy constructor is a special type of constructor that creates a new object as a copy of an existing object.
Copy constructor should have a parameter of the same class type
It is used to create a new object by copying the values of an existing object
It is called when a new object is created from an existing object
A virtual function is a member function that is declared within a base class and is redefined by a derived class.
Declare a virtual function in the base class using the 'virtual' keyword.
Override the virtual function in the derived class using the 'override' keyword.
Use the base class pointer to call the virtual function, which will be resolved at runtime based on the actual object type.
Oops concept refers to Object-Oriented Programming principles and their implementation in software development.
Oops concepts include inheritance, polymorphism, encapsulation, and abstraction.
Inheritance allows a class to inherit properties and behaviors from another class.
Polymorphism allows objects to be treated as instances of their parent class.
Encapsulation hides the internal state of an object and only exposes nec...

Polymorphism can be used to create a Card class with different types of cards. A function can then use polymorphism to randomize the pack.
Create a Card class with different types of cards as subclasses
Implement a function that creates a pack of cards using polymorphism to add different types of cards
Use a random number generator to shuffle the pack
Polymorphism in C++ allows objects of different classes to be treated as objects of a common superclass.
Polymorphism is achieved through function overloading and virtual functions.
Function overloading allows multiple functions with the same name but different parameters.
Virtual functions are functions in a base class that are overridden in derived classes.
Example: Animal class with virtual function 'makeSound', Cat and
STL in C++ provides reusable algorithms and data structures for efficient programming.
STL includes containers like vector, list, map, algorithms like sort, find, and iterators.
Example: vector
STL saves time by providing pre-implemented solutions for common programming tasks.
Design patterns in C++ are reusable solutions to common problems in software design.
Design patterns help in creating flexible, maintainable, and scalable code.
Examples of design patterns in C++ include Singleton, Factory, Observer, and Strategy.
Each design pattern has a specific purpose and can be applied in different scenarios.
Understanding design patterns can improve code quality and efficiency in software developmen
