Git is a distributed version control system used to track changes in code, collaborate with teams and manage project history. It allows developers to work independently on branches, merge updates and revert to previous versions when needed. Git ensures code integrity, supports parallel development, and is widely used in software engineering for efficient source code management and collaboration.
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.
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.
MySQL is an open-source relational database management system widely used for storing and managing structured data. It supports SQL for querying, updating and controlling data efficiently. Known for reliability, speed and scalability, MySQL powers web applications, enterprise systems and cloud platforms. It is commonly used with PHP, Java, Python and modern application stacks like LAMP and MERN.
C# (C-Sharp) is a modern, object-oriented programming language developed by Microsoft for building secure, scalable applications. It runs on the .NET platform and supports features like strong typing, garbage collection, LINQ, async programming and cross-platform development. C# is widely used for web, desktop, game development (Unity), cloud services and enterprise-level software solutions.
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.
Coding problems are exercises designed to test a programmer’s ability to write logic, solve challenges and apply algorithms or data structures. They help improve problem-solving skills, logical thinking and coding efficiency. Common in interviews and competitive programming, coding problems range from simple tasks to complex algorithmic challenges, preparing developers for real-world software development scenarios.
A method is a block of code that performs a task.
In databases, a query is a request to retrieve, insert, update or delete data. Written in SQL (Structured Query Language), queries can be simple, like fetching all rows from a table, or complex, involving joins, conditions and aggregations. They are essential for interacting with and managing database information efficiently.
Technical Interview is a structured assessment where employers evaluate a candidate’s technical skills, problem-solving ability and practical knowledge related to a specific role. It typically includes coding challenges, system design questions, debugging tasks and discussions about past projects. The goal of a technical interview is to measure how effectively a candidate can apply their technical expertise to solve real-world problems.
