I applied online and heard back incredibly quickly, perhaps within a couple of weeks, which impressed me. This was followed by a couple of phone interviews, one with HR and a technical one with existing engineers.

Then, they flew me out and put me up in a pretty nice hotel, with all expenses paid. Once there, I gave a short presentation on my background, which was followed by one-on-one interviews with each member of the group to which I had presented.

These interviews included questions ranging from practical application scenarios ("How would you solve this problem?") to personality and character assessments, and they lasted a few hours.

Up until this point, I was pretty happy. However, I became hesitant when I indicated uncertainty about working 50-60 hour weeks. This was something I hadn't been explicitly told prior to arriving, aside from hearsay. Furthermore, I likely would have been more accepting of this expectation, had I not been in Los Angeles, where a long commute seems guaranteed regardless of employment.

At that point, their response was essentially dismissive.

Technicians are drilling a series of holes around the fuselage. You find that these holes are out of spec in a certain pattern. What do you think might be the cause, and what would a solution be?

(The pattern changes as you walk through different possible causes, ranging from tool wear to differences in operators during drilling, etc.)
