Depending on traffic, the Airtrain/Subway combo may be fastest. I arrived around 2:00 PM and made it to my hotel (2 blocks from the main building) in about 35 mins with no issues. Some folks spent over an hour in a cab due to traffic, but that was in the morning. Either way, try to give yourself PLENTY of time so you aren't stressed and good luck! The interview process is a great experience.
