I applied online and received an invitation for a phone interview very quickly.

Unfortunately, the initial time for the interview was not convenient for me, so I offered to reschedule.

I received an initial positive response to rescheduling, but then there was no contact at all.

After three unanswered emails over the next week, I gave up.

Some weeks later, I received an automated invitation to give feedback on the interview process. I detailed all the above problems with the lack of communication, even clarifying that I would still be interested in interviewing. I received no contact back.
