I did!
Basically it's done via the Cut-e platform, if someone has done the assessment for air-lingus it is quite similar.
You can practise the exercises on the pilotest website (google it) by selecting CUT-E. it is not a 1:1 copy but is very similar.
There are various psychotechnical exercises, including some logical thinking and deductive thinking. Around 30 ATPL questions and a video interview where you have to record yourself in a time limited environment, answering to 3 HR questions.
Overall it's not too complicated and even without practice it's quite achievable. Just brush up your ATPL knowledge and practise in front of a camera if you feel shy of doing that.
Good luck!
