Boeing interview questions

Submitted my resume online and got a call from the hiring manager himself a couple of days later. Just wanted to schedule time for an onsite. The onsite interview was a 1 hour long 4:1 with 4 managers and directors of different levels. It was extremely structured in the question being asked. The hiring manager was actually reading the questions from a document, which I have not seen anybody doing in 15 years for quantitative roles. All the questions were of the "tell me about a time when you had to do this and that". Most, but not all, were quantitative in nature. But also got a couple along the lines of "tell me about a time when you had to reconcile differences with a colleague". No white-boarding at all, which is also usually odd for data scientist positions. I left happy with how the interview went. I usually excel in this type of interviews. What happened next was kind of puzzling. I got a HR person contacting me, telling me that my online application did not match what I had on my resume. So I went in, updated the online application and waited. But nobody ever contacted me again. That's kind of unusual because when you end up going onsite, a recruiter always follows up with some closure (either an offer or no offer).

Spoke with a mechanical engineer at an information session at a conference and was able to line up an interview for the following day. The interview was very basic with 3 behavior questions, typical STAR format. I was then issued a letter of intent the following day. It all happened very quickly and was actually quite surprised at the speed of the offer.
