System design is the process of defining the architecture, components, modules, interfaces and data flow of a system to meet specific requirements. It focuses on creating scalable, efficient and maintainable solutions, covering both high-level design (HLD) and low-level design (LLD). Essential for building reliable, high-performance software systems.
Artificial Intelligence (AI) is the simulation of human intelligence in machines, enabling them to think, learn and make decisions. It powers systems to solve problems, recognize patterns, understand language and adapt over time. AI is used in various fields, including robotics, healthcare, finance and everyday applications like virtual assistants.

A structured conversation where one participant asks questions and the other provides answers of those questions.
DSA (Data Structures and Algorithms) is a fundamental concept in computer science that focuses on efficiently storing, organizing and processing data. Data structures like arrays, linked lists, stacks and trees manage data, while algorithms provide step-by-step solutions to problems. Mastering DSA is essential for writing optimized, scalable and high-performance code.
An interview experience is a detailed account of the interview process for a specific role, covering rounds, questions asked, difficulty level, preparation tips and personal insights to help future candidates understand what to expect and how to prepare effectively.
Low-Level Design (LLD) defines the internal workings of individual software components. It focuses on class structures, object interactions, methods and data flow. LLD translates high-level architecture into detailed designs using principles like SOLID and design patterns, serving as a blueprint for developers to write clean, maintainable and scalable code.
Interview Questions are structured queries asked by employers to evaluate a candidate’s technical skills, problem-solving ability, experience, communication skills and cultural fit. These questions can include HR, behavioral, technical, coding and situational topics to assess whether the candidate is suitable for the job role and organization.
Software design is the process of planning and structuring a software system’s architecture, components, interfaces, and data flow to meet functional and non-functional requirements. It ensures scalability, maintainability and performance. Key approaches include modular design, object-oriented design and architectural patterns like MVC and microservices for efficient, reliable software development.
SQL stands for Structured query language. It is a programming language for storing and processing information in a relational database. It is standard language for accessing and manipulating databases.
