I've heard of people using iPads. Also, the individuals who staff Pilot Recruitment are AMAZING! If you reply to the invite email and explain your situation, I sure they would extend your timeline. Make sure you're comfortable no matter how you accomplish the interview. Remember, this is the first time they actually get to put a face w/ an application...you don't want to mess it up! With that being said, it's a relaxed interview. Just be professional and Good Luck!
