Sample interview questions

React is continuously evolving and a few notable features and changes in React included the introduction of Concurrent Mode for improved performance, React Hooks for state management in functional components, and the Suspense API for handling asynchronous data fetching.


The Context API is a feature in React that allows you to manage and share state data across components without having to pass props down through multiple levels of the component tree. It provides a way to create a global store of data that can be accessed by any component in your application. To use the Context API, you typically create a context object using `React.createContext()` and provide it at a higher level in your component hierarchy. Components can then consume this context using the `useContext` hook.


React Portals are a feature that enables you to render components outside the normal parent-child hierarchy of the DOM. This is useful for scenarios like modals, tooltips, or popovers, where you want to render a component at a specific location in the DOM tree, even if it's not a direct child of the root element. Portals provide a way to render content into a different DOM node using the `ReactDOM.createPortal()` function.


Error boundaries are a mechanism in React that allows you to catch and handle errors that occur during rendering, in lifecycle methods, and in constructors of a component's descendants. They help prevent the entire application from crashing due to unhandled errors in a specific component. You can create an error boundary by defining a component that implements either `componentDidCatch` or the newer `getDerivedStateFromError` lifecycle method. When an error is thrown within the error boundary or its children, these methods are called, and you can use them to handle the error gracefully, log it, or display a user-friendly error message.

Best back-end engineers I've ever worked with.

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly.”
