You will get PHL, if not right away, by the time you hit the line. Commuting from BOS would be easy. Our RSV its not horrible for commuting, you will need a crashpad tho. As long as you get a 9am start time your first day, you can make it to PHL from BOS and be covered by the commuter clause. You can get released from RSV on your last day as early as noon, which makes it easy to get home on your last day. The interviews are really HR oriented. They want to know if you are going to fit in with our culture. You may get a couple easy tech questions on your current twin. Good luck in ATL.
