I agree with PP to be yourself, especially as a live-in. If you are hired to be anyone else, you will likely be unhappy...and unlikely to be in the position longterm. If you are were able to get this far along in the interview process (think of how many candidates didn't even get interviews!) you are likely to be considered for other, similar ones if this one doesn't work out.

Beyond that, I would highlight your specific skills and interests, so they know what makes you special as a candidate. A nanny portfolio or examples from prior nanny logs/photos of projects done with kids* is a great way to give a more vivid picture of yourself.

* Make sure to block any faces, names, or other identifying information.

Stick to your professional standards. Jane of all trades, is the master of none.

Be yourself.

Offer to take .25 less per hour? LOL

I'm in the running for a live-in position in NYC, and I reeeeally want the job! Any advice on what to do or say to seal the deal?
