TuSimple Systems Engineer - Autonomous Vehicle Software Architect interview questions

Recruiter reached out to follow up on my application. 30 minute call with the hiring manager. Follow up call with technical team within a week: 3 members on call, questions were mainly from 1 senior member. Questions were not clear or specific, needed to ask for additional clarification No information provided about the job responsibilities or expectations. Overall, generic job description, generic questions, very secretive post NDA, decent interview questions.
