That is a ridiculous cop-out. Dev work is very regimented for many of us; we have a half dozen regular agile meetings, deployment schedules, etc. The process for code getting accepted and deployed is well-established.

It's very easy to establish a standard response time for getting back to candidates or tell them when you're going to make a selection, and to communicate and enforce a timeline for things like sending and signing documents. I could literally automate most of the process.
