Blue Origin Manufacturing Engineer interview questions

Brief phone screen with HR and then with the Hiring Manager. After these there was a 4 hour interview that included an hour presentation and then 30 minute conversations with members of the team. I enjoyed talking to the team and the only one who asked any technical questions was the hiring manager. Although it went well I never heard back after reaching out to both HR and the hiring manager. Given I spent a decent amount of time on an hour long presentation I would have appreciated some form of feedback.
