Deloitte Business Technology Analyst interview questions

The interview process was great, and I received really strong feedback from the interviewers. But the recruiter tried to ghost me! When I followed up a few times, she told me that the role I interviewed for is no longer needed. A few months later, the entire team was doing mass hiring for the team I interviewed for. If I didn't follow up, I have a feeling I would have never heard from Deloitte again. I find it unprofessional to have someone go through 3 interviews and then say the role isn't needed anymore.
