I applied on Boeing's website, and a couple of weeks later I got an email asking to set up a phone interview. I was surprised to find that the phone interview consisted of just 6 behavioral questions (describe a time when...) and that was it. I got an email about 3 days later to fly me to St. Louis for a plant visit.
That day was great. There were 3 applicants, and we had multiple presentations, a tour, and got brought through their museum. You sit down 1-on-1 with 3 separate managers for about an hour each. Only one asked a few technical questions, but for the most part it was the managers describing what they do. I ended up receiving an offer, I countered, and they raised it. In the end I chose a different company but I was very impressed with Boeing and their benefits.
