Technical round questions assess your problem-solving skills and knowledge in your field, often involving coding or system design.
Common topics include data structures (e.g., arrays, linked lists) and algorithms (e.g., sorting, searching).
You might be asked to solve coding problems on platforms like LeetCode or HackerRank.
System design questions may involve designing scalable systems, like a URL shortener or a cha...
INVEST is a set of criteria used to evaluate user stories in Agile development.
INVEST stands for Independent, Negotiable, Valuable, Estimable, Small, and Testable.
Each user story should be independent from others, negotiable in terms of details, valuable to the customer, estimable in terms of effort, small enough to be completed in a single iteration, and testable to ensure quality.
For example, a user story like '...
Overloading is a concept in programming where multiple functions can have the same name but different parameters.
Functions with the same name but different parameters can be defined in a class
Overloading allows for flexibility in function usage
Example: void print(int num) and void print(string text) are overloaded functions
Function overriding is a feature in object-oriented programming where a subclass provides a different implementation of a method that is already defined in its superclass.
Function overriding is used to achieve polymorphism in OOP.
The method signature of the overridden method in the subclass must match that of the superclass.
The access level of the overridden method in the subclass cannot be more restrictive than t...
Polymorphism is the ability of an object to take on many forms.
Polymorphism allows objects of different classes to be treated as if they were objects of the same class.
It is achieved through method overriding and method overloading.
Examples include function overloading, operator overloading, and inheritance.
Polymorphism helps in creating reusable and flexible code.
