Delta Faucet Company Supplier Development Project Manager interview questions

Standard process - I received an email from the HR Manager telling me that I had a phone interview opportunity with the hiring manager and one of his subordinates. The HR Manager set the phone interview date, and the actual interview was pretty typical. What was not typical was the fact that the hiring manager was not available for the interview. Also, the subordinate that interviewed me was late to the phone call by 10 minutes. All in all, Delta did me a favor by not pursuing me further.
