Ensure the people you pick for your project are the right fit before hiring React JS specialists. Utilize software known as “resume filters” to screen candidates for a similar position.
Once you have the perfect or appropriate resumes, call them. For the telephone interview phase, consider their expertise, experience, skills, background, and knowledge while asking your questions.
Step 3: Assess the portfolio before hiring React JS programmers
Analyze the projects your candidate has worked on in their role. Review their roles and responsibilities, participation degree, project results, achievements, and employer appreciation. When hiring React JS engineers, profile evaluation is an essential stage that must be addressed.
Step 4: Evaluate technical proficiency to hire React JS programmers
Assess the technical proficiency of React JS developers using the questions listed below. By asking them these simple and basic questions, you can analyze and test whether the candidate has the technical background to finish the project successfully or not for your respective client.
Questions for hiring React JS engineers at the junior level
Q1. Does HTML get used in the React framework?
A1. React development makes use of JSX, a JavaScript syntactic extension that is perfect for the HTML documentation.
Q2. What is the model of the CSS box? How do I rearrange the boxes on a web page in a browser?
A2. The CSS box model will describe the rectangular boxes which are based on the visual formatting model and will create documentation for tree objects. The boxes’ positions can be switched using transform, position, and margin.
Q3. In React applications, how do you manage events?
A3. Clicks, keystrokes, and form submissions are instances of user interactions known as events. React offers event handlers that function and are also contained in components. The UI element experiences the associated event, which triggers these functions.
Q4. Describe the Virtual DOM notion in brief as it connects with React.
A4. An in-memory replica of the real DOM is called the Virtual DOM. React efficiently determines the differences between past and current virtual DOM states rather than modifying the browser’s DOM directly, enabling simpler and more efficient UI modifications.
Questions at the mid- level for hiring React JS developers
Q1. Can JS support multiple inheritances?
A1. In JS, a single prototype is linked to every object. JavaScript cannot effectively inherit from more than one prototype chain.
Q2: What is an event loop in JavaScript?
A2. An event loop is an infinite loop that accepts commands, performs them, and then waits for other commands. The event loop continuously monitors the call stack and the callback queue. When the callback queue becomes empty, the event loop adds the next function to the call stack.
Q3. Describe the idea of React’s Unidirectional Data Flow.
A3. In React apps, data is passed and updated in a unidirectional manner. Props allow data to pass from parent components to child components. Newer components are unable to alter the props they are given directly. Instead, they use state management systems such as Redux or broadcast events to cause updates that re-enter the component hierarchy.
Senior-level questions for hiring React JS developers
Q1. Tell us about a React component lifecycle technique you used and why.
A1. componentDidMount():: This function can be used to set up subscriptions or retrieve data from an API. It executes after the initial render.
useState() Hook: (For functional components) This hook can manage the component state.
Q2. How would you optimize a React application’s performance?
A2. Memoization: To prevent needless re-renders, cache component outputs.
Code splitting: The application code is divided into smaller bundles to speed up initial load times.
Lazy loading: It reduces the initial bundle size by loading components only when needed.
Virtualization: Effective methods for presenting big lists, such as windowing.
Q3. How do props and state differ from each other?
A3. Standard JavaScript objects include props and state. Even though they both have data that determines render outcome, the components that make them function differently. The component receives props in the same manner as function parameters. A function declares variables the same way the component handles the state.
