Angelo I did my sim 5 years back on 747. To my mind I was ropey handling wise at best. I'm Airbus rated as was my co-conspirator. We failed to land on either approach, forgot to get the weather and were briefing the Sid and approach into ema as we flew down it. BUT the one thing we did was stay calm, jollied each other along , laughed a little and stayed safe. We both got in. Don't sweat the big stuff , do your best but above all show them you are a calm , professional affable pilot who has a sense of humour under pressure. Good luck. Ps my trimming was abysmal.
