Hi,
For the video interview you have 3 questions with only 1minute prep if not less and they are basic interview questions but what is a little bit difficult is that you only have one attempt when recording. The questions change from one candidate to another as my friend did not have the same as I did.
For ATPL questions I would say it is general subjects so try to review ATPL questions you trained during your training. You will have 30 questions in 10 minutes.
You can train with latest pilot interview prep it s a good package for this kind of assessment.
