Valuelabs Interview Experience | React JS | 5+ Years | Valuelabs Hyderabad

Introduction

I recently had the opportunity to interview with Value Labs, a multinational company known for its innovative solutions. The interview process was conducted virtually via video call, and I would like to share my experience and insights from the journey.

Overview of the Interview Process

The interview was divided into two main rounds, notably focused on coding and technical knowledge specific to React JS. Each round was scheduled for 30 minutes.

First Round: Coding and Technical Questions

The first round primarily revolved around coding concepts and practical knowledge in JavaScript and React. Here are the key questions I encountered:

1. What is an Immediately Invoked Function Expression (IIFE)? Provide an example.
2. What are closures? Explain with an example.
3. Write a function that increments a value x each time it's called, starting from 11.
4. Map an array to output the square of each number.
5. What will be the output of a specific code snippet?
6. How do we call the getName method and what will be its output?
7. What is the output when using an arrow function?
8. Explain the use of const in JavaScript.
9. What are the benefits of using React?
10. What is the Virtual DOM?
11. How can we optimize React applications?
12. How do you diagnose bugs in React?
13. What is setState in React?

I managed to clear this round, which was encouraging for me.

Second Round: Technical Architecture and Project Discussion

The second round transitioned into more architectural and project-related discussions. The questions included:

1. Can you explain your last project?
2. What design patterns did you use?
3. What is the difference between functional components and class components?
4. What are higher-order components and how do they work?
5. Discuss your experience with your projects.

This round was more focused on my past experiences and understanding of React's building blocks. Although I felt I performed well, the HR informed me that I could not proceed to the next rounds. This is often the case when client-side vacancies are not available.

Conclusion

Overall, my interview experience with Value Labs was positive. The questions were relevant and challenging, allowing me to showcase my knowledge in React and related technologies. Despite not moving forward, I appreciate the learning experience and the insights I gained.

FAQ

1. What is an IIFE?

• An Immediately Invoked Function Expression (IIFE) is a function that is executed immediately after creation.

2. What are closures in JavaScript?

• Closures are functions that remember their outer variables and can access them even when they are executed outside their original scope.

3. How can I increment a value with a function in JavaScript?

• You can create a function that maintains a private variable and increments it each time the function is called.

4. What are functional components in React?

• Functional components are JavaScript functions that return JSX and can use hooks to manage state and side effects.

5. Why might an interview be canceled even if it goes well?

• Interviews may be canceled if there are no vacancies from the client's side, despite the candidate performing well in the interview process.
