I applied online and got a phone call while I was at work (I couldn't take it) that went to voicemail. I called them back 1.5 days later and was told to call them back to schedule an interview as they were busy. A few hours after that I got an email saying I wasn't being considered anymore.

It was easy and straight to the point- manager just wanted to make sure I knew what I was getting myself into, like responsibilities expected in the job and whether i was ready/comfortable with it.
