Yep.
Not so much the vetted questions by anyone, but three interviewers taking turns and notes. At least one of my fellow interviewers has had to demonstrate valid interviewing, it was not pretty.
Oh yes we (me and others at my level) do (ask technical questions, we are hiring technical personnel after all).
My typical interviews are 30 minutes to an hour, mostly closer to an hour (on both sides of the table).
