Best of luck for your interview!

Look on the TSA website how things should be packed for your travel-sized liquid toiletries and medications, especially if they are going to be in a carry-on. There is other helpful information on their website for packing. I don't know if you are renting a car vs taking taxi's, but especially if renting a car, I found taking maps ahead of time of the area, printed from home helpful around the hotel and on how to get to the interview.

It sounds like it will be quite an opportunity and so wish you the best for safe travels!
