The straw that broke the camel's back was a project that I had to spend a solid two days on. When the interviewer started with his line of questioning about the code, he seemed to only focus on small, pedantic stylistic preferences, not the code itself or whether it addressed the spec.

Questions like, "Why didn't you log everything as JSON? You know we're going to log this into Splunk." Like, no dude, that wasn't on the spec, and nowhere would I have had the opportunity to read your mind.

This went on. Literally, every criticism was either irrelevant or specific to something not on the damn spec. Not only did I not get the job, but they also told my then-current employer I was on the market. WTF.

Project-based interview with critique.
