Certainly M&B questions will come up along with those centred around the tech log, insurance certificate, acceptable defered defects and MEL. Well they did on mine.
I also got asked about speeds and asked when I would elect to fly a departure at Vx and a definition for Vy.
Some other questions about passenger comfort i.e flying at a higher level when there is turbulance and the safety brief came up (ie it is a legal requirement, so remember to provide one).
Nothing nasty and I've never known of too many nasty questions being asked. So don't fret too much
Goodluck
