I applied through other source. The process took 1 day. I interviewed at Delta Air Lines (Atlanta, GA) in Feb 2012
Interview
The second round interview on-site at Delta is made up of 4 separate interviews (@45min each) covering revenue, marketing, leadership, and cultural fit at Delta. The revenue and marketing portions have several scenario-based quantitative questions. Very well run interview day. Amazing people! Go for it if you get the chance!
Interview questions [1]
Question 1
The leadership and fit interviews contained reasonable behavioral type questions. One of the other two interviews required a mini-case in which you work through a revenue problem.
