European Space Agency interview questions

I applied with an agency, but the interview was with ESA staff. The filling of the ESA form was really intense. I had to make a 15 pages document filling experience on each of the vacancy point. The interview was pleasant. It was on Teams and it lasted 1 hour. I think I did well and apparently I did, according to the agency, they gave me 8 points out of 10 but surprisingly (for the agency as well) I was not selected.
