Indeed Technical Business Analyst interview questions

There are 3 interviews in the process. 1. Technical screening: 30 minutes was a business section and 30 minutes for a coding question. 2. 4 (45 min) interviews lined up: One was a business interview, another product (which was a open ended question), and two more coding. Everybody was friendly. 3. Project deep dive with hiring manager: Talking about a project you worked on of your choice. The process is very very slow and they don't give you feedback. I asked at the end of the technical screening if I did ok and he refused to tell me. After I finished the project deep dive interview with the hiring manager I received a rejection email with zero explanation! I emailed my recruiter trying to get some feedback or something but crickets.
