We cannot state anything based on only an individual experience.
As you know, training is not an easy chemistry which depends on many parameters: the individual, the syllabus, the instructors. If the Ab initio training is not correctly optimised, the induction in Airlines has to be heavier and the overall cost is increased for the same result at the end. So the chain of training has to be considered from zero to an operational first officer, the consistency and optimisation has to be checked along the whole chain.
Unfortunately defects are often detected very lately through incidents. It is all the experience of Civil Aviation which day after day is used to improve selection and training. In my background, I have participate (As defender) in discipline court in a major european airline. Mostly of time I have to acknowledge that the files of involved individuals were already presenting deficiencies in the very ab initio training, the incident was most often a confirmation.
Then there is the adaptation to new technologies, and particularly with arrival of Glass cockpit Airliners. New philosophy and new issues to face.
A trial is just ending in France on the Saint Odile accident: was the map of the EFIS accurate or shifted by 2 Nautical miles? We cannot rely idiotement on the information given by a computer, from time to time a "bug" is introduced in the calculation chain. Maybe by our mistake, maybe by a faulty DME and a stormy environment as it seems to be the case for the Mont Saint Odile. In any case, a proper knowledge (and practice) of those modern technologies must be acquired. The less expansive is to do it during the Ab Initio training. Modern tools have to be used like FNPT (Flight Navigation and procedure Trainer). Some schools have done the investments, some not yet.... Maybe cadets coming from the last category are still comfortable on a classic airliner, what about the next generation?
In any case, experienced crew on the last generation of aircraft underline that, contrary to what initially the manufacturers were saying, you must have a sound knowledge of your aircraft and its systems if you do not want to be trapped one day. As an example the A 320 type Rating excessively minimised 10 years ago has inflated slowly ...
