Challenge

Create a simple consumer loan app. The app is a headless web service that exposes the following endpoints:

• Apply for a loan and provide loan amount, term, name, and personal id
• List all loans by a borrower (you can skip AuthN and AuthZ)

Lending rules:

• Monthly interest rate: 5%

Reject the loan application if:

• Borrower is blacklisted (store blacklisted personal ids in a config file or a database)
• Too many applications from one country in the last 24 hours

Use a 3rd-party service to resolve a country, and store it in a database, together with a loan application.

Technical requirements

• Use Java programming language
• Use any JVM language for tests
• You have total control over frameworks, tools, and libraries

What gets evaluated

• Conformance to business requirements
• Code quality (we value good OO design guided by tests)
• Checkout-and-run convenience

Happy coding! 👨‍💻
