Pretty straightforward. They will ask usual questions marriage, single, any plans, kids, where do you see yourself 5 years from now, what skills do you have, strength and weaknesses, why should we hire. They may seem distracted but that's probably an act so don't bother. There will be a change in the if you say married or plan on kids because there will be questions on that. You can just say what you feel because of you are planning then you are.
