I was asked to take a assessment and then called upon for a interview where there asked basic questions like what's your background and how well do you think this roll fits you and what's your thoughts on this job basically like what I think of the job and the nature of the job

I gave assessment and then I manager interview round online, it was scheduled for 30min but manager took only 10min for me and later said OK I'm done. Now I'm literally thinking did I will get offer letter or not. Any one who gone through this interview please share your thoughts.
