Hate to point out the obvious to fellow aviators, but generally there are a number of factors that lead to an incident like this.
Pointing at the hours of pilots may or may not be relevant.
There would most likely be a number of factors at play, (outsourced training providers, fatigue, cultural factors, SOPs etc) the list is almost endless.
Don't rush to blame the pilots involved, as easy as that may be.
This is where a governing body should be investigating the reasons behind this incident, if in fact the operator has not recognised the deficiencies and addressed them appropriately.
