Good question, and one the whole aviation world either waits on holding their breath or allready has a fixed opinion about.
Anyway, just reread part of the last interim report and lack of experience in manual flight is something i cannot really see there, but probably lack of recent experience as that is not mentioned. The captain hat extensive experience in a lot of types without much automation, the youngest FO had a glider license and should have known about aircraft energy states and how that changes in a dynamic situation. The older FO renewed his SEP rating (in europe its only valid for some time and has to be renewed) in 2005.
All in all not that bad, and still it wasn't enough.
