Top 30 Full Stack Developer Interview Questions & Answers 2023

It is vital in the prevention of unauthorized access to programs and resources in the runtime. It can provide limited access to the code to perform only certain operations rather than providing all at a given point in time. The ability to develop classes, libraries, and APIs and run, debug, and deploy code onto web services and applications form are the key uses of this framework.

It continuously checks the message queue for new events to process and runs the corresponding event handlers. On the other hand, asynchronous programming refers to a programming model where the program execution happens in a non-blocking and parallel manner. In this model, multiple tasks can run simultaneously, and the execution of one task does not depend on another. In synchronous programming, the program execution happens in a sequential and blocking manner. This means the code lines are executed one after the other, and the program has to wait for the current operation to finish before moving on to the next one. Promises provide an interface for dealing with asynchronous operations, allowing chaining of .then() and .catch() methods.

What is an Application server?

Use these 15 Hadoop interview questions when preparing for your next interview. Don’t forget that practicing your programming skills is one of the best ways to prepare for your interview. Solving problems with code will keep programming concepts fresh in your mind. Plus, you might even solve a problem or experience a challenge that you can discuss in your interview. As a Full-Stack Developer, this is a concept you want to be familiar with. An application server allows you to design and maintain applications on both the server- and the client-side.

Caching is a term used when the data has to be temporarily stored in the memory so that an application can access it quickly rather than looking for it in a hard drive. This speeds up the execution to an exponential pace and helps massively in terms of performance. It is put into place to ensure that the application developer is capable of inter-language operations if required. It is a reusable aspect among all of the .NET compatible languages. It is used to provide the instructions required for operations such as memory handling, exception handling, and more. It can also provide instructions to initialize and store values and methods easily.

Reactive programming is a programming paradigm that revolves around using data streams, such as events or changes in variables, and reacting to them. It allows for asynchronous, event-driven programming and can help create efficient and resilient web applications that can react automatically to state changes. Reactive programming can enhance code maintainability, expressiveness, and simplify complex asynchronous scenarios. Pair programming helps teams to collaborate and share knowledge among the members. As two developers work together to complete the task, it ensures better code quality.

Vuex provides a single source of truth for application state and allows for predictable, atomic state updates via actions, mutations, and getters. Controlled components have their form input values controlled by the component’s state via event handlers, while uncontrolled components rely on the DOM to manage input state. For example, the execution stack and program counter must belong to that thread.

What do you mean by promise, also explain its states?

It contains a comprehensive service layer model and supports various protocols and application programming interfaces (API). Cross-origin resource sharing (CORS) is a process that utilizes additional HTTP headers to tell browsers to provide a web application running at one origin. Web scripts can be integrated using CORS when it requests a resource that has an external origin (protocol. Domain, or port) from its own. Understand the required skills and qualifications, anticipate the questions you may be asked, and study well-prepared answers using our sample responses.

The View component is responsible for displaying model objects inside the user interface. The Controller receives the input and calls model objects based on handler mapping. It also passes model objects to views in order to display output inside the view layer. The questions that are asked in a full stack developers interview are quite different from the regular web developer technical interview questions. This is primarily due to the difference in the job roles of the two positions. That data can be used to POST, GET, DELETE, and OUT data types, which refers to reading, deleting, creating, and operations concerning services.

Hibernate removes boilerplate code that comes with JDBC API.

Multi-threading is achieved by executing several processes that the operating system supports. A Request Dispatcher is an interface in Java Servlets used to forward a client request to a resource or include the output of another resource in the response. It helps to divide a web application into small modular components, making it easier to maintain.

It supports a lot of languages, and you can work with everything from C# to VB all the way to Perl, and more. Carlos is a professional software engineer and full-stack web developer specializing in the Ruby on Rails framework. He has worked with tech companies for over a decade, helping to build technology-based businesses from the ground up. He has a bachelor’s degree in computer science from Williams College. Submitted questions and answers are subject to review and editing, and may or may not be selected for posting, at the sole discretion of Toptal, LLC.

We can easily fix it by using the following methods:

It also helps in detecting bugs easily and identifying the scopes for improvement. Besides that, pair programming promotes better communication between team members and builds a positive work environment. Multi-threading is a process that is used to improve CPU performance. Through this process, multiple users can manage the program at the same time, or the same user can manage several requests simultaneously.

  • Here, the interviewer wants to know your understanding of the subject and the proficiency with which you can handle tasks and solve problems.
  • It also gives unique class names, allowing you to assign the same class name in different namespaces.
  • Plus, you might even solve a problem or experience a challenge that you can discuss in your interview.
  • JDBC and Hibernate are Java technologies used for managing relational databases.
  • In this section, we have collected some full-stack developer interview questions that can help you to crack the interview to get your dream job.
  • For example, development and IT departments work in cross-functional teams, combining their strengths to create software.

The interviewer asks this to assess if you have had any experience learning .NET development in your degree course. An entity called the garbage collector is used to allocate and de-allocate memory as and when required by an application. This is done by performing checks on the references of variables and objects used by the application. If an object is no longer required by the application, the memory is de-allocated and freed up.
