For us, it's not all about an outstanding CV or a long list of qualifications. We are far more interested in your approach when faced with a concrete challenge. What is your way of thinking? How do you tackle the problem? Which tools do you choose?
In order to gauge these qualities, we have created a challenge for you to complete. This is a simplified case which illustrates the kinds of situations we have to deal with on a daily basis. This challenge is an opportunity to demonstrate your capabilities and to show us your coding craftsmanship.
There are no time limitations, but our suggestion is that you spend no more than a few hours completing the challenge. We are not after a bullet-proof solution. What is important is a clean, maintainable and intuitive result.
Create it in your own way and use the tools you are most comfortable with. Show us your skills!
The human population is quickly overwhelming the Earth's resources. We must find a solution to control the exponential growth of human beings. The Governments of the world, along with the most intelligent people on the planet, have found a solution.
Every person, upon reaching their twentieth birthday, has to compete in a live or die fight against another fellow. The competition has been designed using a systematic process to select the most skilled individuals of our society based on their intelligence, agility and strength.
The competition is called Rock-paper-scissors-lizard-Spock - here are the rules.
You are in charge of implementing the interface that every person has to use to fight for her survival.
The Player enters in a web site and she can choose between:
- Generate a new Game (The system will offer a UUID for the new Game)
- Compete in a Game that is waiting for an adversary (the Player inserts the UUID of the Game)
Then the Player creates a list of 10 moves. For each one the Player can choose one of the following options:
- rock
- paper
- scissors
- lizard
- spock
The system will store the Game configuration and will keep it until an adversary chooses to fight against this Game.
Once the system detects a match it executes the competition and stores the results.
Both Players can see the results and prepare themselves for a long life or... impending death.
We know this project would typically employ a websocket based implementation, but this is excessive for the purpose of this challenge. In the Waiting for an adversary page you can just expose a refresh! button so the Player can click on it to ask the system if there are already results for this Game.. or you can implement a X seconds authomatically refresh.. or an Ajax solution.
- Please check the wireframes
- Please check the workflow diagram
This wireframes and workflow diagram are a very minimal explanation, please feel free to add/remove/modify anything on your own.
Please don't get caught up trying to implement the perfect solution, we are interested in the most simple and functional solution. We expect the final delivery to be stable, so focus on simplifying the functionalities to allow a working solution to be developed in a few hours.
The backend must be Ruby. The frameworks, gems, and databases are all up to you.
For the frontend, we appreciate if it looks human friendly, but it is not necessary to be fancy. (There are a lot of OpenSource/Free templates and HTML/CSS frameworks that do a good job.)
