The initial phone screen was by appointment. Spent 20 minutes going over my background, WHY I wanted the job, a discussion of a role that seemed to be a little different than the rest (I pointed out the similarities in terms of function and expected results and this seemed to please her). It was a thorough phone interview, and the interviewer seemed intelligent and knowledgeable about the role. I say this as I had one phone interviewer recently who didn't understand the role beyond the bullet points on the job spec. The difference is immense, and even if not me, I'd say the hiring manager will be presented with some good candidates to choose from.
