  Are you willingto relocate? Ans: A stack is a Last In, First Out (LIFO) data structure. You can only add and remove components from the top. A queue is a First In, First Out (FIFO) data structure. You add things in the back and remove them from the front. Ans: OOP is a programming paradigm that uses "objects" (instances of classes) to model real- world entities. The four main principles of OOP are: Encapsulation: Wrapping data (variables) and methods into a single unit (class). Inheritance: One class (child) can inherit properties and behavior from another class (parent). Polymorphism: Ability to take many forms. It allows objects to be treated as instances of their parent class. Abstraction: Hiding the complex implementation details and exposing only essential features.

  Read More: Top50+ Java Interview Questions & Answers. Answer: One quick and straightforward Agile method for describing a feature from the viewpoint of the user is to utilize a user narrative. "As a [type of user], I want [some goal] so that [some reason]." Similar to practical development tools, user stories facilitate communication between all stakeholders and guarantee that the end product satisfies user needs. You can concentrate on delivering the most crucial components first by using them to assist in prioritizing features according to user values. Answer:Scrum, an Agile method, emphasizes teamwork, responsibility, and making consistent progress toward your objectives. Sprints are small, manageable pieces of work that last two to four weeks. You're all prepared to keep on track with responsibilities like Development Team, Product Owner, and Scrum Master, as well as frequent meetings like Sprint Planning, Review, and Retrospective. This strategy allows you to receive continual input and continuously improve so that you can produce excellent items faster. Answer: The Waterfall approach requires you to finish each step before going on to the next, much like a straight line. Gathering requirements is the first step, followed by design, implementation, testing, and deployment. It's similar to having a defined structure. Projects with clear criteria from the start are a good fit for this approach. In contrast, Agile is like a flexible path that allows for changes and continuous input from clients. It is like working in sprints, where each sprint includes design, development, and testing all in one go. This approach is like being perfect for dynamic projects, as it embraces modifications even after the work has begun. Q26. What is the significance of the Minimum Viable Product (MVP) in Agile development? Q24. What are user stories in Agile, and how do they benefit the development process? Q25. What is the Scrum framework, and how does it fit into Agile methodology?

  Read More: Top50+ Python Interview Questions & Answers. Answer: AnMVP in Agile development is a product with only enough features to draw in early users and collect feedback. With this method, you may test your ideas without having to commit to a full-scale launch right away, and it saves money and development time, among other important benefits. Through gradual learning and development, this approach guarantees that the end product meets the demands of real customers and the market. Answer: There are several normal forms, each addressing specific types of redundancy: First Normal Form (1NF):Ensures that all columns contain atomic values and that each entry in a column is unique. Second Normal Form (2NF):This is achieved when a table is in 1NF, and all non-key attributes are fully functionally dependent on the primary key. Next, let’s go over some specific technical questions you may encounter. These questions will help you demonstrate your skills and knowledge in various technical areas! Answer:Database normalization is a way to organize your database so it works better. Instead of having big tables with lots of repeated information, you break them into smaller, related tables. You follow rules called normal forms, like 1NF, 2NF, and 3NF, to help you do this. By reducing redundancy, you avoid storing the same information in several places. For example, you keep a customer’s contact details in one table and link it from others. This saves space and makes updates easier since you only have to change the information in one spot. Normalization also keeps your data accurate and speeds up performance. With everything organized, you’re less likely to have errors from duplicate information, making your data more reliable. Plus, when your data is structured well, queries run faster, helping you find what you need quickly. Overall, normalization makes your database easier to manage and allows it to grow as your needs change. Specific Technical Questions Q28. Can you explain the different normal forms in database normalization? Q27. What is database normalization, and why is it important?

  The system allowsdeadlocks to happen but monitors for them. There are a few ways to deal with deadlocks. Here are some solutions: The system avoids deadlocks by making sure at least one of the conditions that cause deadlocks doesn’t happen. It is like organizing people so that only one person can enter the narrow door at a time to prevent them from getting stuck. Imagine two processes, Process A and Process B. Process A has resource 1 and needs resource 2. Process B has resource 2 and needs resource 1. Both are waiting for the other to release their resource, and this creates a deadlock where nothing can happen. Third Normal Form (3NF): A table is in 3NF if it is in 2NF and all the attributes are only dependent on the primary key, not on other non-key attributes. The system checks before allocating resources to ensure a deadlock won’t happen. It is like checking if the path is clear before letting someone go through the door so they don’t get blocked. A deadlock happens in an operating system when two or more processes are stuck waiting for each other to release resources. None of them can move forward because they all need something that another process is holding.It is like two people trying to pass through a narrow door at the same time, but both are blocking each other, so neither can move. Q29. Explain a deadlock in operating systems and how to resolve it. What is a Deadlock? Example Deadlock Avoidance Deadlock Prevention How to Resolve a Deadlock Deadlock Detection and Recovery
• 14.
  If a deadlockis detected, it takes action to break the deadlock by killing or restarting some processes. It is like letting two people get stuck in the door and then asking one to step back so the other can pass. If a process waits too long for a resource, the system might stop it and release its resources so others can continue. It is like setting a timer. If someone takes too long to get through the door, they have to step aside and try again later. In the HR interview at Tech Mahindra, it's all about getting to know you better. They want to understand your personality, career goals, and how you handle different situations. You’ll be asked questions about your background, strengths, weaknesses, and scenarios to see how well you fit into the company’s culture. It's a chance to show them who you are beyond your technical skills! Answer: A system call is a programming interface that allows user-level processes to request services from the operating system's kernel. These services can include hardware access, file management, process control, and inter-process communication. System calls provide a controlled interface for processes to interact with the system's resources, ensuring security and stability by preventing unauthorized access to hardware and system resources. Answer: A process is an executing program in its own memory space, while a thread is the smallest unit of execution within a process. The parent process and the child process are defined in the same memory area, which means that threads communicate and occupy resources more efficiently. This also means, however, that if not synchronized correctly, threads can interfere with one another, while processes cannot. Resource Allocation Timeout Common HR Questions Q30.
