That's easy. Just say I will never compromise on writing unreadable and messy code. I will also never compromise on documentation. That's just a disservice to my team members and disrespectful to anyone who will ever read or modify the code.

That bullshit will work for both technical and non-technical people. Of course do I do follow my own mantra all the time? Does anyone follow it at at all times? No.

You need some kind of coding question at the very least to measure coding ability and a non-technical person just can't do that.
