Assignment for Java Backend Engineer candidates in Eleveo.

This project contains an assignment description and definition of the API needed to fulfill the assignment. Also, a prepared example of client implementation is provided.

As a personal shopper, you have a rich client. They frequently ask you to buy new cars as an addition to their garage. Today they requested the following:

I don`t care about the car price, I want to buy the 5 most powerful ones - the ones with the highest horsepowers. But I only want at most 2 cars with the same engine type (DIESEL, UNLEADED, HYBRID, ELECTRIC).

Your assignment is to implement a piece of code that will satisfy your customer's demands for today only. Note that many parts of this assignment are intentionally oversimplified.

You have the following limitations:

• implement the CarShopper interface as provided - without changing it
• adhere to the car shop API as defined via openapi.yaml,
• do not spend more than 1 hour on this (you can invest more, but please be honest and inform us)

Other than that feel free to:

• use any library or client of your choice, you don't have to use the provided ones
• write any tests you prefer (feel free to use the provided test or test data as you see fit or not at all)
• restructure the project as you see fit, but keep in mind that it is not part of the assignment

This project contains a prepared implementation of a client application without the required business logic implemented. You can use it to help you with implementation. The project consists of two submodules.

• car-shop-api-client - contains OpenAPI definition of car shop API to be used in the assignment and   plugin to generate Spring WebClient API Client to help you with the implementation of the assignment.
• car-shopper - project with dummy client using car shop API (see DummyCarShopper class).   You should create your own CarShopper implementation that will fulfill the assignment.   You can enhance the prepared test/ add more to cover the newly implemented solution.

Provided project is Spring Boot 3.0 application in Java 17 built by Gradle. To build and execute tests install Java 17+ and then run:

./gradlew clean test --info

• fork the repository
• create a branch identified by your name
• implement the assignment
• create a Pull Request to the main branch of original repository
