ProQuest Content Editor interview questions

A recruiter reached out to me to schedule a phone interview (via email) which I did. The recruiter did not call me at the arranged time, or respond to emails I sent asking to try to set up another time. A week later I get a call with no warning asking if I'm ready to interview, which I wasn't able to do at the time, so we rescheduled for later in the week. Again, I received no call or communication from the company. Incredibly incompetent recruiters.
