Online application in October / November 2012. Phone interview prompted with a late night message from human resources 3/11/13. Phone interview caller id was 00 so answer If you see this. Returned call placed in voice mail and I tried 3 more days until they finally returned the call 3/13/2013. I had a very young women on my call. She didn't seem very eager to listen to my responses and I had a hard time understanding her questions. I answered the customer issues she asked with the suggested system - sympathize, apologize, reason and solution format. She asked if I was able to fly to Atlanta in the middle of the interview but at end said a senior manager would return call. I knew at that time I didn't get to the next round of f2f interviews. This was my second attemp with delta in the last 3 years. Interview format The first group of question involves on board issues with a drunk passenger, a women refusing to check extra carryons, and others. The second group of questions is all about improving safety in the work place and your own personal customer service experiences.
