Q1. What motivated you to pursue full-stack development?
Ans - I was motivated to pursue a career in full-stack web development due to my genuine passion for technology and problem-solving. My journey began when I created a project website, and I was captivated by the ability to turn design to a web page. I was inspired during my learning journey at iNeuron, where excellent course and mentors reinforced my choice. It's a field that offers constant learning and the chance to impact the digital world, making it a perfect fit for me.
Q2. Describe the MVC (Model-View-Controller) design pattern.
Ans - MVC is an acronym for Model-View-Controller. It is a design pattern for software projects. The advantage of this is it helps in focusing on a specific part of the application name, the ways information is presented to and accepted from, the user. It helps in allowing for efficient code reuse and the parallel development of the application.
Model - Model represents the structure of data, the format and the constraints with which it is stored. It maintains the data of the application. Essentially, it is the database part of the application.
View - View is what is presented to the user. Views utilize the Model and present data in a form in which the user wants. A user can also be allowed to make changes to the data presented to the user. They consist of static and dynamic pages which are rendered or sent to the user when the user requests them.
Controller - Controller controls the requests of the user and then generates appropriate response which is fed to the viewer. Typically, the user interacts with the View, which in turn generates the appropriate request, this request will be handled by a controller.
So, basically -
- Model is data part.
- View is User Interface part.
- Controller is request-response handler.
Q3. What is the difference between GET and POST HTTP methods? Can you provide an example of when you might use each?
Ans - The GET and POST methods are two of the most commonly used HTTP methods, but they serve different purposes and have distinct characteristics -
-
GET - GET is primarily used for requesting data from a specified resource. Data is appended to the URL as query parameters. This means that data is visible in the URL, which can have privacy and security implications. The amount of data that can be sent in a GET request is limited by the URL length, which varies between browsers and servers.
-
POST - POST is used for submitting data to be processed to a specified resource. It is often used when data needs to be sent to the server for further processing or when sensitive information should not be visible in the URL. Data is sent in the request body, which is not visible in the URL. This makes it suitable for sending larger amounts of data and for transmitting sensitive information like passwords. The amount of data that can be sent in a POST request is not as constrained as in GET requests. It can handle larger payloads.
-
Example -
-
GET - When I am implementing a search functionality in my project. Then I can use the GET request.
-
POST - When I am implementing a sign up/log in functionality then I have to use the POST request because we are submitting a sensitive information like password while logging in.

Q4. How would you explain responsive design to someone who isn't familiar with web development?
Ans - Responsive design is a web development approach that ensures a site looks and works well on all devices, from large desktop screens to tiny mobile phones. Responsive design adjusts the layout, text, images, and interactions of a website to fit the screen it's viewed on. This means users get an optimal experience, whether they're on a computer, tablet, or smartphone, without needing a separate site for each device. It's about making the web accessible and user-friendly, regardless of the device people use to access it.
Q5. HTML/CSS Test: Create a basic webpage layout using HTML and CSS. This should have a header, a main content area, and a footer. Bonus points for responsiveness.

Q6. JavaScript Basics: Write a function that takes an array of numbers and returns the sum of all even numbers.
Ans -
const sumOfEvenNumbers = (numbers) => {
let sum = 0;
for (let i = 0; i < numbers.length; i++) {
if (numbers[i] % 2 === 0) {
sum += numbers[i];
}
}
return sum;
};
const numbers = [1, 2, 3, 4, 5, 6];
const result = sumOfEvenNumbers(numbers);
console.log(result); // Output will be 12 (2 + 4 + 6)Q7. Basic Interaction: Create a form that collects user input, validates the input, and then displays it on the page using JavaScript.

Q8. Simple Logic Test: Write a function that determines whether a given string is a palindrome.
Ans -
const checkPalindrome = (string) => {
const len = string.length;
for (let i = 0; i < len / 2; i++) {
if (string[i] !== string[len - 1 - i]) {
return "It is not a palindrome";
}
}
return "It is a palindrome";
};
const string = "abbbba";
const value = checkPalindrome(string);
console.log(value);Q9. Basic Database Query: Given a database table structure, write an SQL query to fetch specific data (e.g., all users aged 25).
Ans - The basic syntax of the query will be SELECT column1, column2 FROM table1, table2 WHERE column2='value';
If we take the example of all users aged 25 then the query will be like this -
SELECT * FROM users
WHERE age = 25;Q10. API Basics: Explain what you understand by RESTful API and why it's used.
Ans - A RESTful API (Representational State Transfer) is an architectural style for designing networked applications. It uses a set of constraints to create web services that are scalable, stateless, and easy to understand. RESTful APIs are widely used because they enable efficient communication between client and server applications over the HTTP protocol. They use standard HTTP methods (GET, POST, PUT, DELETE) to perform operations on resources represented as URLs. This simplicity and adherence to HTTP standards make RESTful APIs a popular choice for building web services, allowing systems to interact, exchange data, and achieve interoperability, making them a fundamental part of modern web and mobile app development.

Q12. How do you approach a problem, especially when you're unfamiliar with the challenge?
Ans - When faced with an unfamiliar problem, I follow a systematic approach -
- Understanding: I thoroughly read and dissect the problem statement, ensuring I grasp its requirements and constraints.
- Research: I conduct research to gather relevant information, concepts, or techniques related to the problem.
- Plan: I devise a structured plan, breaking the problem into smaller, manageable tasks.
- Experiment: I implement and test solutions incrementally, starting with the most straightforward components.
- Iterate: If necessary, I refine and iterate on my approach based on the outcomes of initial attempts.
- Seek Help: If I'm stuck, I seek guidance from documentation, peers, or online resources.
- Patience: I remain persistent and patient, knowing that tackling complex problems often requires persistence and creative thinking.
Q13. Describe a project or assignment you've worked on during your education that you're particularly proud of. What did you learn from it?
Ans - In my final semester project I made a MERN stack video streaming application with features like - sign up/log in, explore different movies and web series of different categories, add or remove favorite, add or remove comments etc.
I learned so much from this project. Basically how everything works in a full stack app, how to design database schemas, how I can manipulate the database from our app. I learned how to use API endpoints. I learned to implement sign up and log in functionality. I also learned how to use MUI(React component library) for the UI components for our app.
Q14. How do you manage your time and prioritize tasks, especially with tight deadlines or during exam periods?
Ans - In tight situations or during exams I follow some techniques to manage time and prioritize tasks effectively. At first I try to find all the works that I have to do and I try to break everything on the basis of these things - Deadline, estimate time to finish it, difficulty etc. On the basis of these thing I set a priority on each tasks and finish them one by one. I also see if some work is super important and needs to be done as soon as possible, then I have to do that task first. In exam times I generally try to fix a time-frame in a day where I will study the exam subjects and this time-frame depends on the exam syllabus. Other time I do the other important works like assignment submission or making projects. In these kind of situation I generally take small breaks sometimes like 10-15 mins of break for refreshment only if the situation allow me, otherwise If I have to work whole I do that also.
Q15. Can you describe a situation (academic or personal) where you had to work as part of a team? What role did you play, and what did you learn from the experience?
Ans - In my last semester project of my MCA I worked with my 4 other friends in a team to build a full stack video streaming application project. In that project I worked as a team lead. It was a complex project for us especially because we were all still learning MERN stack at that time. I coordinated tasks among all of then and guided them when needed. I earned valuable experience like leadership. I also got valuable skills of decision making and problem solving. Not only these, I also gained experience of teaching a little bit. Because one of our teammate was very new to JavaScript, so, I taught her JavaScript and that time I also realized how much I enjoy sharing my knowledge. These are all the experience and skills that I gained from the project.
Q16. Imagine you're stuck on a coding problem for a while. How would you go about seeking help or solutions?
Ans -When faced with a challenging coding problem, I first attempt to solve it independently by breaking it into smaller parts. If I'm still stuck, I try to find relevant documentation, books or solutions from any other online resources. If I still don't get the solution I seek help from my friends, forums or online communities, where I provide a clear description of the problem and the steps I have taken. I value diverse perspectives and am open to constructive feedback. I also engage in discussions and brainstorming if necessary. Ultimately, I learn from both the success and setbacks to enhance my problem-solving skills.
