Applied through an online job board. Received a call for interview within a week. First they called to ask if I know Excel and if I am familiar with booking airline tickets, car rental and hotel accommodations online. I responded with a yes, they said they will call me back. They called back after an hour and set up an interview.
On the day of the interview, they will give you 'critical thinking' type of test, where you have 20 minutes to make an Excel table and also search and book a flight, car rental and hotel online.
