Taking the subway will be faster than driving and much cheaper than a cab. I'd estimate 30-45 minutes via subway if you don't get terribly lost and follow these instructions...
Take the Orange Line at Temple Med, someone will be able to direct you to the nearest subway stop, ask them for the Erie stop -- it's a block up from the interview building, MERB. Take the Orange Line ($2 exact change) going south bound (To South Philadelphia). Try to get on the express train if possible -- but either way you'll be ok. Get off at 15th street and transfer (free) onto the Blue Line (Market-Frankford line), and take it going Westbound, towards 69th street. Get off the Blue Line at 30th street station. At 30th Street Station, ask someone to direct you to Regional Rails. Find Regional Rails and take the Regional Rail train going to the Airport (Airport Line). This will cost you $6.25 if you buy the ticket at the 30th Street Station. It will otherwise cost you $7.00 if you pay for your ticket on the train. The train stops at specific airport terminals, so know which terminal you need to get off at. In my opinion, this is the fastest way of getting from Temple to the Airport. I assume you're not going to have a car since you're asking about the airport. Secondly, a cab will cost you $28.50 (without tip) and you'd have to deal with rush hour (great movie) traffic. If you follow these instructions, it's really straight forward. Although the people in Philly aren't the nicest, someone will likely help. Good Luck on the interview!!!
