First interview was with a company executive, second interview was with communications director, then the next few meetings were scheduled with key team members.
Although they had questions relevant to the role prepared and went through them, my interviews were more conversational style.
Although initially there seemed to be a strong match, the second interview must have brought up some concerns that I am not really sure were fully communicated back to me.
In general, I have a good impression of this division of the company, and it seems like it would be a positive environment to work in.
One unique feature of this experience was that the first interview was not with HR (which is usually a redundant layer that often confuses the process), but with a company executive.
They were professional, and respectful of my time.
