I took a cab for my interview from JFK airport , it was nearly 50 bucks , if your in no rush take the AirTrain and Subway. Cost 7 bucks or so and drops you off literally right in front of the building ... On the way back everyone is headed to the airport so we spilt a cab with 5 people and shares the cost . Way back plenty will be going back to JFK and LGA.

Good luck and get there early ,
