It's not so much about arrogance as a strong opinion on technical issues and direction. I'm also interviewing for roles at a level where guiding the direction is part of the job.
I've had a pretty good history of seeing shifts in technique and technology over time. Usually advocating a couple years ahead of broader adoption.
Being an advocate for change can be frustrating in and off itself. Especially when that change being advocated is in some regards a return closer to a previous approach.
I've been an early adopter several times. I've also resisted some shifts along the way. It's not always about change right now, but getting thoughts out in the wild.
