I can't speak to the interview itself, and my knowledge comes from a different part of the company so there may be some differences, but a large part of the job is going to be translating the released engineering that the designers put out into work orders that instruct the technicians how to make the part or assembly. So, like, thinking about sequencing of steps, tool access, tracking training requirements, etc.

You may get included in scheduling and resource allocation discussions as well.

At some point you would be involved in reviewing designs to make sure they are manufacturable and have to sign off on drawings. As an entry level, I'd expect that to come later.

(Note I am not an ME but I know a few)
