In order to be considered for this position, you must complete the following steps.

Note: This task should take no longer than 1-2 hours at the most.

Prerequisites

• Please note that this will require some basic knowledge and/or the ability to learn of the following: - Python - Django - Git - Docker - Any type of DB of your choosing

• You will need to have the following installed to complete this task - Python - Docker - Azure

Task

1. Fork this repository
2. Create a source folder to contain your code.
3. In the source directory, please create an Django app that accomplishes the following:
   • Create a function(s) that solves the coding problem in the next section below
   • Create an API that allows you to post two lists of the events as specified in the Problem section below and returns the list of conflicting events. Use JSON.
   • Write tests that adequately test the functionality.
4. Dockerize your application by writing a docker.yml file and test it by running the container locally.
5. Commit and Push your code to your new repository
6. Send us a pull request, we will review your code and get back to you
7. Deploy this docker image to Azure. I will need to give you access to this via skype or email.

Calendar Double Booking Conflicts

At Voyajoy, each home that we manage is listed on multiple short-term rental platforms like Airbnb and VRBO/Homeaway. We put it on multiple rental platforms because it helps listings reach more potential renters. Listing on multiple platforms, however, is a problem because each platform maintains its own calendar that are not synced with each other which leads to potential double bookings. Because of that, we need a way to detect double bookings for each listing. Please develop an algorithm that takes calendar events from multiple calendars and return a list of conflicting events.

Input: Two lists of events in json format

[ { "name": "Booking Event Foo", "checkIn": "2016-07-12", "checkOut": "2016-07-19"}, ... ]

[ { "name": "Booking Event A", "checkIn": "2016-07-07", "checkOut": "2016-07-14"} ... ]

Output: List of conflicting events

[ [ { "name": "Booking Event Foo", "checkIn": "2016-07-12", "checkOut": "2016-07-19"}, { "name": "Booking Event Bar", "checkIn": "2016-07-07", "checkOut": "2016-07-14"} ], ... ]

First figure out the different types of conflicts that can happen and then run some test data once you have your algorithm written.

NOTE: checkIn of one event can match the checkOut of another event. This is because generally, a guest can checkout on the same day another guest checks in

Tests

Create the following unit tests with the testing framework of your choice:

1. Write a few tests that tests the above problem. Write as little or as many tests as you see that is appropriate.

Once Complete

1. Commit and Push your code to your new repository
2. Send us a pull request, we will review your code and get back to you
