The process was fairly simple most NASA internships don't have any technical leetcode style questions its mostly just a behavioral interview where you describe some of the projects you worked on and general things like how you work in team settings

Pretty straightforward, one question that did stuck out to me was being asked about my favorite subject in school. It was a behavioral interview so no technical questions were asked. Some other questions asked were what's your strength, what's your weakness, etc. Although, I did end up getting ghosted by them afterwards. Didn't receive my rejection until months later.
