I applied online by first sending in my resume. A few days later was sent a link to HireArt to complete a 7 question interview that had video portions. It was easy enough but took me forever because I kept re-recording. Waited over a month and finally got an invite to the group interview aka hire meetup. There were about 25 or so other candidates and about 8-10 current Airbnb employees. The process took a few hours, was less scary than I'd worked myself for, and involved some role-playing, survival team-building scenarios, and short one-on-one interviews. The next day I was asked to do a Skype interview with someone in Dublin. Still waiting to hear back but I think it went very well and felt natural. Basically, Airbnb staff members are really chill, respectful, and easy to talk to. Research company culture and policies. A billion bonus points if you've used the site as a guest or host and like to travel.
