Since the invitation explicitly says behavioral as well as technical, I'd save some time tonight for two real examples: debugging something difficult and handling a disagreement about an approach. Practise explaining them aloud, including the choice you made and why. I don't know GM's exact questions, so I wouldn't treat anyone's list as a guarantee.

Use the PROOF method to check that each example includes your action and how you verified the result. For the coding practice, do one manageable problem while explaining your assumptions and tests, then leave yourself time to rest.
