Ask you basic interview questions about the projects you have worked on, the machine/deep learning skills you have. Also your availability for the job and work timings. they also let you know the salary offered for the role.

Fair, interviewer was quite passive, so you have to be proactive in introducing yourself, experience, etc. Not much to share, just be sure to understand your resume bullet points in a comprehensive way, i.e dont f around with the interviewer, they know everything. Interview ethics is also important, over confidence or under confidence can be a red flag
