Freeport-McMoRan Process Automation Engineer interview questions

I got a screening call from the HR for the role. The interview was scheduled after a week since i got the call. Later, since the hiring manager was busy, the interview was postponed by two weeks. And, on the day when the interview was supposed to be held, it was cancelled. I did not receive any other details. Later, after calling the HR a few times, i got a reply that the position was closed. I had to wait for a month to know that i would never get an interview at Freeport.
