My first assessment

Passed Class 1 two weeks ago. Applied for numerous jobs. This one has come back and said they'd like to assess me in a Class 2 (tomorrow) then give me training and start me if ok in Class 2 then further on assess me here in Class 1 for the job applied for. I've never driven a Class 2 but guess it's very similar as in lines I take at junctions etc , stay straight turn late? Have driven 7.5t for many years so guess it's just a bigger version. It's tail lift and cage work which I'm unfamiliar with. Have done parcels for 30yrs. Anything you think I should be prepared for? Also first interview in 28yrs
