HII Unmanned Systems interview questions

HII contacted me by email and scheduled a standard phone interview for a remote position. The hiring manager asked about my experience using their stack, but did not have a hands-on technical interview.

HR representative interviewed me was friendly but felt unorganized. Both the HR interview and technical interviewing with the team went well. The technical team was friendly and knowledgeable. However HR representative never followed back up and in the end it felt unprofessional.
