I applied online, then they called me for a phone interview, then a first HR interview, a second HR interview and agent interview, and lastly one final skype interview with Global Head of PA ops. The interviews with HR were pretty basic, just wanting to get to know you etc. The interview with the agent was really tough, they were trying to intimidate you. The interview on skype was horrible, like a personality quiz, prepare your 3 reasons why this, 3 reasons why that, 3 qualities good, bad, what you want in an employer.
