The interview had several stages:
1- Phone call with HR. I was asked about my professional background, qualifications, relevant experience, and the reasons I chose to apply for Workday;
2- Skype call with a US-based hiring manager. I was asked for more in-depth information about my relevant experience, as well as theoretical and practical aspects of the job (what software I use, what's my approach, had I worked as part of a SCRUM team before, etc.)
3- On-site interview. I had a total of 7 interviews in succession - 2 face-to-face interviews, following with 5 video calls with various people in the States.
Everyone I interviewed with was friendly, helpful, and very open about providing information concerning the position and the company in their turn. One of the best interviewing experiences I've had so far.
A few days later, HR called again with an offer, and I accepted on the spot.
