We prefer C#, but other languages are also fine
If you prefer to implement it in a different language, let us know beforehand.
-
It's not a riddle
If something isn't clear, ask us. Don't waste time on figuring out or guess our intentions when they're not obvious. We appreciate feedback.
-
The code should be clean and readable
There's no need for over-engineering but we do wish to see a good separation of concerns. The code should be simple, clean and testable. It should align with the SOLID principles.
-
It needs to work
We want to see a working solution, even if it's not complete. A compiled and running code with missing features is better than a solution that doesn't compile or errors out.

Use in-memory storage
Do not setup a real database. Use static members or any in-memory storage library. Still, adding a persistancy solution shouldn't require a complete refactor of your project.
We want to build a REST API for a dog shelter. Users will be able to register dogs in the system, and query available dogs by size category.
A user should be able to add a new dog to the system. The new dog request should include the dog's name and breed.
Before saving the dog in the in-memory storage, the service should find the dog's breed in the following public dog API:
https://api.thedogapi.com/v1/breeds/search?q=canaan
This third-party API returns a metric height (minimum and maximum). You should calculate the average - in this example the average height is 54 ((61+48)/2).
[
{
"weight": {
"imperial": "35 - 55",
"metric": "16 - 25"
},
"height": {
"imperial": "19 - 24",
"metric": "48 - 61"
},
"id": 66,
"name": "Canaan Dog",
"bred_for": "Guarding flocks and encampments",
"breed_group": "Herding",
"life_span": "12 - 14 years",
"temperament": "Cautious, Devoted, Alert, Quick, Intelligent, Vigilant",
"reference_image_id": ""
}
]The average height should be stored together with the dog name and breed.
A user should be able to find all dogs of a certain size category. The size categories are:
- Small: Smaller than 35cm
- Medium: Between 35cm and 55cm
- Large: Bigger than 55cm
For example, by querying all dogs of the small size category, I should see the dog Pugster in the response, if Pugster was registered as a Pug breed.
Cover your code with unit tests as you see fit.
This is an optional bonus question - We respect your free time and do not require or expect you to complete this bonus question. It is only provided as an oppurtinity for you to "show-off" your coding and design skills if you choose to do so.
- Add the capability to filter dogs by their breed.
- Add the capability to filter dogs by their temperament. In the example above, requests for a dog with a temperament of "Vigilant" should return Canaan dogs. As you can see in the public dog API, each dog can have several temperaments.
