Leidos Principal Computer Vision/Machine Learning Engineer interview questions

Received interview schedule request with recruiter. Recruiter was out of office for a week when I followed up. Recruiter then casually threatened to withdraw interview when my schedule did not have short-term One hour call with the team lead on MS Teams. The team lead did not use video or introduce themself and went straight into technical questions. It honestly just seemed like the interviewer was soliciting solutions for their current working problem.
