Expedia Group Software Development Engineer interview questions

There was a tech question at the career fair, and then an onsite interview which includes three rounds. The first round was a brain teaser interview. The second round was a recursive programming question. The third round was questions on objective programming.

contacted by a recruiter several days after apply online. set up a phone screen the next day and on-site two weeks later. Then the recruiter told me the feedback is good and want to setup another phone call with the hiring manager from the team I was assigned. And then I was told the manager doesn't think I am a good fit?!!!!! This is my whole interview process, it went well and I enjoyed it at the beginning, but then it just getting weird.
