If you’ve arrived at this page you’ve passed the first stages of our recruitment process and we’re interested to see what you can do.
Below are the details of a short test we’d like you to complete and send back to us, we’re not expecting you to spend days on it, just a couple of hours to give us an idea of your skills.
Our coding test starts by downloading this data file…
This is a file of data on different flights around the world over a two week period, we’d like you to create an API that to provide access to this data, we’d then like you to use this API to do some basic analysis on the data it returns. Finally, we’d output the results of your analysis to a web page.
Write your server code in either NodeJS, Perl or Python, feel free to use any helper or third party libraries you find useful.
For your output, use whatever technology you feel comfortable with to provide your results on a web page.
The data lists different flights and if that flight has more than one segment (where you need to change plane) then it lists out the different segments included in the flight.
The important things to know are:
– All airports are given as standard 3 letter IATA codes.
– fields prefixed with dep relate to the flight departure.
– fields prefixed with arr or dest relate to the flight arrival.
– Most of these flights are return flights so they have an outbound and an inbound leg, this is shown in the file as fields prefixed within or out.
You should produce an API designed to run as a web service that can output the flight data provided above in a JSON format.
You should then create a web-page that that can retrieve the data from your API, and process it to produce the following data points:
– How many of the flights depart in the morning (before 12 AM)?
– What percentage of the total set of flights fly into Sweden?
– What are the 10 most popular destination airports?
– What’s the average journey time between London Heathrow (LHR) and Dubai (DXB)?
– At least one other statistic that you find interesting
Things to Think About
Some other things that aren’t requirements, but you might want to think about:
– How to structure your code? Well structured code helps anyone who comes to read your code later.
– How to interact with your API? Think about how your API could be used, and what data someone might need.
– What technology to use for your output? Many libraries such as react have many helper function to allow you to get your data and form your output.
– How to format your output? A good presentation can make all the difference to a user of a system.
Send us an email with your code to email@example.com you can include your code by any of the following methods:
– A link to a public GitHub repository with your submission.
– A zip file containing your submission.
– A link to a cloud-based folder with your submission
Make sure to include a README file with instructions on how to install and run your code.
We look forward to receiving your submission.
