Crazy Cards Application

You have been asked to develop a web application to allow customers to enter their details and review credit cards that are applicable to their credit status.

Different people have different credit statuses based on personal characteristics including their financial history, earnings, where they live, employment status and so on. The individuals credit status, or score, dictates which cards are available to a user.

This application will be a simplified version of this real world scenario.


  • The user should submit their details via a form.

  • The application should then return a filtered list of cards available to that user; use the rules outlined at the end of this document to decide whether a particular card is available.

  • The user should be allowed to select one or more of the returned cards and see the details for the cards selected.

  • When multiple cards are selected, the total amount of credit available to the user on those cards should be displayed.

What we expect

Beyond meeting the spec outlined above, we would like to see a solution which demonstrates the following:

  • Familiarity with React and the use of components

  • Extensible logic (e.g. resilient to addition of cards and/or card availability rules)

  • Good application architecture

  • A sensible approach to testing

Brownie points for:

  • Responsive web design

  • Mock endpoints

  • Hand-rolled server configuration
