I applied in-person. The process took 2 weeks. I interviewed at Hilton (Los Angeles, CA) in Sep 2013
Interview
Manager of the Hotel and Head of HR both interviewed me for about 20 minutes. Manager asked most of the questions but the HR woman made sure to ask the required Hilton protocol interview questions.
I applied online. The process took 2 months. I interviewed at Hilton (New York, NY) in Apr 2016
Interview
I had a video interview, it took less than 20 minutes. They asked me 6 questions about previous sales experience and any other experience that gave you a lesson. And also they asked me about salary and working shift. It was pretty smooth precess, but it is really difficult to answer.
