Guittard Plant Manager interview questions

I was contacted by an internal recruiter. Had a phone screen with recruiter. Requested a job description. Did not supply one. Called me back and talked with Dir. of Production on the phone for 45 minutes. Again, requested a job description, none supplied. The next week was asked to come to the plant. Met with Dir of HR and Dir of Production for 2 hours. Again asked for job description, none supplied. They made it clear they were not in a hurry. Two days after I receicpved a rejection form letter, they place a job posting on LinkedIn based on my interview, including the salary range. Underhanded and dishonest the whole time. Who interviews without a job description ?
