I had the weirdest job interview for a contracting job at Delta. I passed two technical phone interviews and was scheduled for an in-person interview. The night before it dumped a ton of snow. I tried to cancel, but didn't have the manager's contact info. I left an hour early to get there, and still I was 5 minutes late.

They let me sit in the lobby for another twenty minutes, then the Manager's "administrative assistant" came and fetched me. The Manager then asked me some of the most condescending questions, like "what operating system do you use? Have you ever used Linux?" He then finished with a snide comment and that our time was up and he had a meeting to go to.

I called the recruiter from my car. They decided pass, "because the Manager said I didn't apologize enough for being late." That was the last I heard from the recruiting company. They ghosted me. Wouldn't talk to me or respond to my email. It was the most unprofessional situation I've run into in 25 years of contract/consulting. Just plain weird.

Note, this job was not to code, but write documentation about the code. They wanted a C++ programmer to document the existing system that schedules and reroutes flights during irregular ops, that was written by some guys from Bell Labs running on some fault-tolerant hardware. He had sold the management on converting everything into Java running on commodity/cloud servers.

Every time I see their system meltdown... I'm reminded of this.
