Executives have very little time and they really value it like basically every highly successful person does. I say that for 3 reasons: one is somebody (and possibly not the executive but somebody who works closely with them) has considered you valuable enough that you are worth knowing so that's a good thing and a high compliment. The other is when they say 'personal' don't expect it to be about your life... it will be career focused... Highly likely very little will be about each other's families and hobbies. The last thing is the executive doesn't need you to know them as much as they need to know you if they are asking for your time. All that's to say that a get to know you meeting isn't close to an interview, but it is mostly going to be about you.

With time being valuable, you need to be able to tell them what you or your team does in like 60 seconds and make sure you can speak to like 1-2 really cool things your team and you have done. Not too much detail just what's been done to add value lately and focus on the added value. You'll get asked about next role you want and career aspirations... be ready for that and be direct and open... no answers like 'I'm open to anything if the opportunity is right'. Of course you are so that's a bull**** answer... they want to know what you WANT to do not what you are open to.

In terms of questions, ask a few things around your company's strategy, how your team fits in, his perception of it and where it could improve. At the end of it, ask for a frequent catchup.
