Delta Air Lines Project Leader interview questions

The interview process was pretty straightforward and painless. The recruiter contacted me about a week after submitting my resume online and set up an interview with the hiring manager which was conducted over the phone. I was then contacted about a week and a half later to have an onsite interview with leadership in the group for which I was interviewing. I was then contacted about 2 weeks later with an offer from the hiring manger. I thought the process was a bit strange in that there was never a conversation about salary expectations prior to the offer - I only provided history on the application.
