The process consisted of 1) a screening phone interview with the recruiter 2) a 1.5 hour phone interview with the hiring manager and another team member 3) 3 hour in-person interview 4) second 3.5 hour in-person interview. The correspondence from the HR manager and recruiter were both professional and prompt. While I did not ultimately get the job, I felt they were both professional and didn't leave me hanging as many companies do.
The in-person interviews were very difficult. While the hiring manager asked questions that pertained well to the job and my general philosophies and thinking, I spoke with him in total for over 3 hours. I felt as though he should have been able to ferret me out more quickly than that if TripAdvisor wasn't going to move forward with an offer. The interview with the global director of the communications team was grueling. While he was nice and had a number of insightful questions, several of those he asked could only have been answered by someone who was previously employed by the company. The CMO seemed to have her mind made up based on my resume before even meeting me, and was flatly rude at several points.
