Honeywell Production Engineer interview questions

I applied through my university job board and received a phone call informing me they would fly me out for a job interview at a hiring event. The hiring event consisted of a presentation on how great the company is and why you should work there. There were about 75 people there, and the interview was about 45 minutes long. I had no idea they were hiring people strictly from this interview only. Within four days I received a phone call informing me that they were offering me the position.
