Rockwell Automation Sales Communication Manager interview questions

I applied for the role over a month ago and received a phone call out of the blue from a recruiter asking for a 20-minute interview for the role. I obliged, but didn't have much time to speak, and the exchange became a formal interview. The recruiter stated they'd get back to me either way in a few hours after speaking with the hiring manager. I received no response. It's unprofessional to not set up a proper time to speak to a candidate and interview on the spot. While I went through the process this time, I would urge others to tread lightly if they are treated the same. Candidates are worth a formal process and genuine interest.
