Intuit interview questions

The interview process was simple. 1. HR round 2. SQL assessment 3. Interview with hiring manager and team 4. A4A case study Presentation 5. 3 back to back interviews for follow up on the presentation and general questions It took 2.5 months to go through all these rounds. In the end everyone ghosted me. No proper feedback. Everyone said good things during the interview and then when I reached out to get some kind of feedback no response what so ever. Final comms: Recruiter said they filled the role - this was a while back but I still see the same postings on their page and on LinkedIn being promoted for hiring. I am confused, why lie? I was following up with them even after 4 months of my time investment to get some kind of feedback - apparently feedback is confidential. How will I know what went wrong if you can't provide feedback?

I applied through referral, the first round was a screening call where I was given a coding question, and then I also had an AI round where a basic prompt was given and I was asked to improve it.
