I had perhaps the most amazing interview experience recently where it was an open discussion. It wasn't a technical drill down but more a Q&A where you discuss topics relevant to the area you claim to have knowledge of and how it relates to the job you're interviewing for. It was the complete opposite of code this technical problem and a missing semicolon will get you a flat out rejection.

What clicked was I was finishing their sentences and knew precisely what they were asking. It was an incredibly rewarding experience which led to a same day offer.
