G'day - if your interview is, say, in PMQ, you will need to use the company sops checklist, 138 items or not!
All checkrides will be the same, you have to use the Company SOPS. And yeah - the suggestion that you need to be up to speed on systems is spot on - they won't worry too much about checklist compliance in an initial checkride provided that you are up to speed on your systems and emergency procedures. Like the man says "Commonsense my boy, commensense."
Cheers.
