Every Utkrusht test shows the candidate a real code challenge that they will

face during their job and observes their ability to:

find faults, suggest improvements, etc.

Sample Questions:

Sample Questions:

  • You have a React component with the following implementation for fetching data:

    import React, { useState, useEffect } from 'react';
import axios from 'axios';

function DataFetcher() {
  const [data, setData] = useState(null);

  useEffect(() => {
    axios.get('/api/data')
      .then(response => setData(response.data));
  }, []);

  return <div>{JSON.stringify(data)}</div>;
}

    Discuss any safety concerns or potential inefficiencies in this implementation and how you would address them.

  • In the following code, a parent component passes a list of items to a child component. The items are supposed to be displayed as a list, but nothing appears on the page. Identify the issue and suggest a fix.

    // ParentComponent.jsx
import React from 'react';
import ChildComponent from './ChildComponent';

const ParentComponent = () => {
  const items = ['Apple', 'Banana', 'Cherry'];
  return <ChildComponent items={items} />;
};

export default ParentComponent;

// ChildComponent.jsx
import React from 'react';

const ChildComponent = ({ products }) => {
  return (
    <ul>
      {products.map((product, index) => (
        <li key={index}>{product}</li>
      ))}
    </ul>
  );
};

export default ChildComponent;
