Requires solid mastery of React with hooks and TypeScript. Familiarity with the controlled component system, Ant Design's Form API, and the theming system with Design Tokens is essential for working efficiently on real Ant Design projects.

Use cases

Real Projects

Ant Design is used to develop:

  • Complex dashboards and admin panels
  • Enterprise management systems with advanced forms
  • Backoffice platforms with data tables and filters
  • Applications with complex workflows and multiple views

Types of Company

Ant Design is adopted by:

  • Tech companies with internal management products
  • Startups with enterprise-oriented SaaS platforms
  • Organizations with complex admin portals
  • Companies developing internal tools for teams

Production Scenarios

Ant Design is widely used in production environments such as:

  • Interfaces with complex tables with sorting, filters, and pagination
  • Multi-step forms with advanced validations
  • Dashboards with multiple interactive data components
  • Applications with interface-level permission and role management

Scalability

Ant Design offers multiple mechanisms to scale applications:

  • Design Tokens for consistent theming at scale
  • Tree shaking to import only necessary components
  • Ant Design Pro as a base for enterprise dashboards
  • Deep customization with ConfigProvider

Advantages and Disadvantages

Advantages

Over 60 high-quality enterprise components with a consistent API.

Full TypeScript support with well-defined types.

Mature design system with Design Tokens for deep theming.

Disadvantages

Large bundle if tree shaking is not correctly configured.

Highly recognizable default aesthetic that requires customization to differentiate.

Learning curve on complex components like Table and Form with their extensive APIs.

Comparison

Advantages of Material UI

  • More flexible theming system with sx prop
  • Greater adoption in the Western market
  • More neutral and customizable design

Considerations

Material UI follows Google's Material Design and has greater adoption in Europe and America. Ant Design has richer APIs for enterprise components like Table and Form, with greater adoption in Asia and complex management applications.

Basic questions

Ant Design provides high-quality React enterprise components like Table with sorting and filters, Form with complex validations, and advanced DatePicker that would be costly to implement on top of Bootstrap. Being a native React library, integration with React state and logic is direct and without adapters.
Ant Design is preferable for management applications with complex tables, forms with multiple fields and validations, or backoffice-type workflows. Material UI is more suitable when following Material Design or when the product's visual design requires greater customization.
It allows customizing the theme at the semantic token level without writing CSS, changing primary colors, border radii, spacing, and typography consistently across all components. Ant Design 5 replaced Less variables with CSS-in-JS with tokens, improving theming flexibility and performance.
For complex forms with multiple fields, synchronous and asynchronous validations, dependencies between fields, dynamic forms with fields that are added or removed, and multi-step forms. The Form API automatically manages state, validation, and error messages declaratively.
By importing components individually from their specific path instead of importing from the root package, and configuring the babel-plugin-import plugin or using ES module imports that Ant Design 5 natively supports for automatic tree shaking.
It is the component that provides global configuration to all Ant Design components within its tree, including the theme with Design Tokens, the locale for internationalization, the default component size, and the CSS class prefix. It is placed at the root of the application.
Using ConfigProvider with the corresponding language locale from Ant Design's localization packages for internal component texts like DatePicker, Table, and Pagination. For the application's own texts, it is combined with libraries like react-i18next.
In enterprise applications with complex data tables, extensive forms, multi-step management workflows, or dashboards with multiple types of interactive components. The visual consistency and API richness of its most complex components save weeks of development in this type of project.

Technical questions

By configuring the Table component with the onChange prop that receives pagination, sorting, and filter parameters when any of them change. With these parameters, the backend request is built and the dataSource is updated with the results. The loading prop manages the loading state during the request.
Using the getFieldValue method within validation rules to access other field values, or with the dependencies prop on Form.Item that indicates which fields should trigger revalidation of the current field. For complex validations, a custom validator with asynchronous logic is used.
Form.useForm is the recommended hook that returns a form instance with methods to manipulate values, validate, and reset the form. The ref is the legacy way to access the instance. useForm is preferable because it is more ergonomic with TypeScript and works correctly with the React hooks lifecycle.
By passing a theme object to ConfigProvider with tokens to customize in token for global tokens and in components for component-specific tokens. Changes are automatically applied to all components without additional CSS, and multiple themes can be created to switch dynamically.
Using the Form.List component that manages arrays of fields with add and remove methods. Each field in the array has its own namespace in the form, errors are displayed correctly per field, and validation works independently for each list element.
Using useQuery for data fetching with pagination, sorting, and filter parameters as part of the query key. When the user interacts with the table, parameters are updated in local state, React Query refetches automatically, and loading and data are passed to the Ant Design Table component.
Select provides a list of predefined options with search within them. AutoComplete suggests options as the user types but allows any free text value. Select is used when options are closed while AutoComplete is for searches with suggestions where the value may not be in the list.
By implementing server-side pagination to avoid loading all data at once, using virtual scrolling with Table's virtual prop available in recent versions to render only visible rows, and memoizing columns and dataSource to avoid unnecessary rerenders of the Table component.

Advanced questions

Using Ant Design Pro's scaffolding with its predefined layouts, route-level permission system with access.ts, data models with @umijs/max, and ProTable and ProForm components that extend base Ant Design components with additional enterprise functionalities like persistent column configuration.
By managing the active theme in the application's global state with Zustand or Redux, passing the corresponding theme to ConfigProvider as a reactive theme prop. Ant Design 5 with CSS-in-JS applies theme changes without reload, allowing dynamic theme switches from dark to light or between client themes in real time.
By creating a wrapper component that accepts the same props as the original component plus additional ones, using composition instead of modifying the base component. The extension is documented internally and the Ant Design version is kept fixed until compatibility with each update is verified.
By verifying that interactive components have accessible labels with htmlFor or aria-label, that tables have correct headers with scope, that modals manage focus correctly, and auditing with axe-core integrated in tests to detect accessibility violations automatically.
By creating an internal library that extends Ant Design with business-specific components, a centralized theme with the brand's Design Tokens, documentation with Storybook, semantic versioning, and distribution as a private npm package. Products consume the internal library instead of Ant Design directly.
Using the official codemod that automates much of the API changes, migrating the theming system from Less variables to Design Tokens, updating deprecated components like Grid to new equivalents, and verifying visual changes on each page with visual regression tests before deploying.

Common interview mistakes

Still using Less variables from Ant Design 4 or not knowing how theming works with ConfigProvider in Ant Design 5 reflects being out of date. The change from Less to CSS-in-JS with Design Tokens is one of the most relevant changes between versions.
Importing all of Ant Design without configuring tree shaking generates unnecessarily large bundles. Not knowing how to configure optimized imports reflects inexperience taking Ant Design projects to production.
Manually managing complex form state with useState instead of using Form.useForm, Form.List, or Ant Design's validation rules reflects not having worked with the library on real enterprise projects.
Choosing Ant Design without being able to articulate what it provides over Material UI or Chakra UI in the project's context reflects a lack of judgment. Being able to explain when Ant Design's enterprise components justify its use is expected.
Not knowing Ant Design Pro as a scaffolding solution for complex management applications reflects not having investigated Ant Design's complete ecosystem. For enterprise projects, it is frequently the most suitable base.
Developing multi-language applications with Ant Design without configuring the locale in ConfigProvider generates internal component texts in English mixed with the application's language. It is a visible error in production that reflects inexperience with the framework.
