Ready to get a job as a full-stack developer? Worried about your interview? It's natural to be nervous about interviews, especially for first timers. In current times, there is a huge demand for full-stack developers. It is one of the highest-paying jobs as of now
Full-stack developers are known to manage both front end and back end development. They have a wide range of skills and the necessary expertise to fully develop websites.
Since the average salary for a full-stack developer is quite high, organizations tend to follow a very stringent recruitment process while hiring a full-stack developer. When you are well-prepared and know your concepts well, you can crack the interview easily.
In this blog, we have discussed the top full-stack developer interview questions job applicants and candidates are asked during their interviews.
Full-stack development is concerned with the all-around development of a website or web application. Both the front end and back end are developed simultaneously. The process has three parts:
Full-stack developers have the knowledge to develop an entire web application/website. They are skilled in both front-end and back-end technologies and can develop both server and client software. They are familiar with programming databases, browsers, and servers. They are experts in using CSS, HTML, Java and Python.
To develop a project from the beginning, a full-stack developer needs to have the knowledge of the following:
Full-stack developers are all-rounders. They have knowledge of all elements of software development and are skilled in multiple technologies. There are more chances for software development to function smoothly, efficiently, and quickly. Chances of miscommunication are fewer. Full-stack developers can easily communicate with project managers and IT departments.
As the name suggests, pair programming involves two programmers working at the same workstation. Both programmers have different duties. One works as a driver (writing the code) and the other works as a navigator/observer (views and checks every line of the code). The programmers typically switch their roles at any time. There are three possible pairings in this situation - newbie with newbie, expert with newbie, and expert with expert.

Inversion of Control, also called IoC, is a principle of software engineering used to make classes loosely coupled. Using IoC makes classes easy to maintain and test. It primarily means that the control and dependencies of the objects are transferred to a framework from the main program.
Cross-Origin Resource Sharing, or CORS, enables a browser in a domain to make cross-domain requests. This means a domain can request resources from another domain but only restricted resources can be requested. CORS helps provide some flexibility to the same-origin policy.
Also called Pyramid of Doom, Callback Hell is a slang term used in asynchronous JavaScript. This typically happens because of the difficulty level of asynchronous JavaScript and poor coding practices. In essence, callback hell happens when there are many asynchronous functions and since they are interdependent, they can get messy.
MVC and MVP are architectural patterns. They are used while designing a website. Model View Controller, or MVC, helps develop Java Enterprise Applications. It gets its name from the fact that it divides an application into three parts: model, view, and controller. All three parts have separate functions.
Model View Presenter, on the other hand, comes from MVC. In this pattern, view and controller are divided into view and presenter. The role that the controller performs in MVC is performed by the presenter in MVP.
Some of the differences between MVC and MVP are as follows.
Dependency injection is useful as it provides/injects objects with their dependencies. It is a design pattern that ensures that objects don't have to construct them. A dependency can be injected through a setter or constructor injection. It has the following types of classes:
There are many ways to enhance a website’s efficiency and increase its scalability. Some of them include the following:
Get and Post have many significant differences. Let us discuss some of them.
GraphQL and REST have many differences. Some of them include the following:
Continuous integration, called CI, is a practice under which developers merge their code changes many times a day into a shared repository. This enables them to find problems and solve them early. Software development is a long and time-consuming task and CI helps make it faster and less risky.
Some of the advantages of CI are as follows:
Continuous delivery, or CD, is a practice in which changes in the code are built, tested, and deployed to production automatically. This enables fast and easy release of the software.
The differences between CD and CI are as follows:
Multi-threading allows more than one user to simultaneously run the same program. It is the application/operating system’s way of multi-tasking. This ability also allows the program to handle multiple requests from one user at the same time.
Some of the benefits of multi-threading are as follows:
RESTful (representational state transfer) API is an architectural style that allows developers to create HTTP requests and receive responses.
Some of the differences between abstract and interface are as follows.
There are primarily three types of design patterns. They are as follows:
There are many ways to decrease the load time of an application. These include the following:
The following architectural designs are commonly used:
Just like Callbacks, states of promise handle asynchronous operations. However, promises are much better at handling errors and reading codes. There are three states of promise:
ACID is an acronym for Atomicity, Consistency, Isolation, and Durability. It is used in database systems and is a set of properties that enable the reliable processing of transactions in the database.
Referential transparency refers to replacing an expression while ensuring that the final result of the program remains unchanged. The key is that the program's behavior stays unchanged regardless of whether an actual value or reference value is used.
The ones discussed above are some of the top full-stack developer interview questions and answers asked from candidates striving for careers in full-stack development. These will help you prepare for your interview. An interview can be a tricky experience when you don’t have good communication skills to express your knowledge. So, focus on developing your interpersonal skills as well while preparing your technical knowledge.
