Expedia Group interview questions

I had an initial call with HR, then with the hiring manager who gave me a very little business case to see how I think, and then 3 interviews with team members/stakeholders. After the whole process the result was negative, but supposedly the feedback about me as a candidate is possible. My only regret is that they make you illusioned thinking you are moving forward in the process, and with the feedback, but it is the 2nd time it happens to me.
