The problem with SO to A330 FO Conversion is that Qantas give no consideration to the fact that SO’s haven’t effectively flown for many years. They do a bog standard A330 conversion, there is no extra sim sessions concentrating on normal operations in the circuit, really working on that last 1000 feet. When I did mine, there was also a high failure rate, probably same reasons. Thise who failed were sent to 330 SO, what use is that. All that is needed in 2-3 sessions working on approach technique.
