Is this normal to ask during interviews?

I recently did an interview at Denny’s for the host position and was asked what my weakness was. I said that not asking help and being too independent use to be one but I worked on and continue to do so as I realized being a communicative person and team member was important for the restaurant industry.

I was the told my the AGM that not asking for help and being too independent is not a weakness. Did I mess up when I said that? I feel like with the context I provided, it made sense. Would you consider it a weakness?

Also, I kept being asked what my plans in the restaurant industry was and I was willing to stay vs it being temporary. I’ve never been asked repeatedly what my plan was in the restaurant industry in term of it being long lasting. They talked about if I planned to be a supervisor, AGM, and MG when I stated I would be starting college in the fall for the first time.

Any thoughts?? Maybe it’s a standard question but at one point I sat there thinking that i’m not going to be in the restaurant industry for the rest of my life. I’m going to work at other places and get a job after my education.

I was asked to attend a second round interview.
