Blue Origin interview questions

First interview was about 30 minutes over the phone with another Engineer. The next interview was all on Teams and had to give a 30 minute presentation followed by five individual 30 minute interviews. Presentation had to include 5-6 specific items. Several days later this response was emailed, "We wanted to inform you that the position has been temporarily closed as we reassess our hiring timelines. However, we plan to reopen the role at a later date and would love to keep your application on file for future consideration." I probably spent over 15 hours getting ready for this interview and the company spent 3-1/2 hours interviewing me.
