DevOps/SRE. Our technical interview is pretty regimented and cookie cutter. Over the course of one hour we cover a wide base of practical knowledge to validate the candidates existing knowledge or their ability to quickly acquire the needed knowledge (use of google/stack overflow is encouraged).

As an icebreaker, I pick out items from their resume that stand out and look like strengths. My goal is to play to those strengths and get them comfortable talking about their past battles.
