I had honnestly exactly the same feeling after the assesment . The assessors were so neutral that no one could affirm if he is hired or not , even if you think the assessment was good for you ( As I thought and actually that was confirmed few days later ) .
This description is very similar to my personnal interview , same HR questions , same rwy 27 in liverpool , same SID , same app ....
I hope it will help someone .
