Recruiter screen by phone or interview, 30-45 min hiring manager conversation, and then panel / presentation interview or additional stakeholder interviews. General questions about related experiences, motivations for applying to the role, and behavioral questions. There were no challenging technical questions. At most I was asked to create a forecast, but Excel was sufficient for that.
The recruiters and hiring teams generally don't respond for days or weeks and just ghost. It's best to not taking interviewing for Royal Caribbean seriously especially if you are more than qualified or applying for a Lead+ senior role. It can be good for interview practice if you get to the panel stage. Bring your expectations down to the floor and be sure to have other options. One of my best professional experiences was taking a full-time offer while interning with RCG because they had already shown no interest in hiring me full-time despite HR being bothered that I needed to leave my internship after a month for a full-time role in another state.
