Will I get an offer ? Last round of interview with an HR

I have been through 2 rounds of interviews in a big logistics company in Denmark. I completed and presented the case study which went so well. Then I am scheduled to have the last round of interview with the HR and she sent me an aptitude test and personality test to complete which are also now done.

I am think about if I am going to get an offer on the day of the interview or will they still have to interview more candidates for this one last round?

It is mentally draining to prepare for interviews and all these multiple rounds, case studies, test assessments take so much time and energy especially when you have small children.

Will they give me an offer or will still drag me around?
