If you are selected, you will be sent instructions to complete a small project. There is no time limit to delivery and all I can say is: for me, it was really fun! I did learn a bit in the process. I believe they manage to understand some things with this project: if you really want to work there, if you know WordPress, if you are capable of making decisions and being autonomous in your work. I do advise anyone that does this, to take high-level notes on the steps to complete the project – I did and it was really useful later on.
