I had to undergo 2 skype interviews and a long 2.5 hours of F2F interview. All the interviewers asked the same set of questions in F2F. My only feedback please respect the time and stress the applicant has to undergo for the same pointless questions being asked again and again. Why not have a panel and conduct interviews, all the stakeholders can get the idea at the same time. Trust me with the interview questions combined from all the 5 people without repeating the questions, could be completed in 45 min.
