I am currently interviewing for jobs, and I have encountered several multi-round interview stages. These schools identify a round 1 with 10 + phone interviews; a round 2 with 5 candidates for Skype interviews; and a round 3 for an on-campus visit with teaching demonstration for 3 candidates. When I got my current job, I just interviewed with one person first by telephone then on Skype. I did not visit the campus, nor meet with other faculty/administrators/staff. Which is more typical? The lengthy multi-round job interviews with multiple visits or the one interview with one person format? Any advice on interviewing for a lengthy process like this one I am mentioning?
