Indeed interview questions

I applied online after seeing the opening on LinkedIn and was shortly after contacted for a screen by an internal recruiter. I passed this screen and within a week or so was invited to a first interview, which was a 30-minute presentation followed by some questions with a manager in both Client Success, and the partnered Account Management team. All seemed to go well and I was told I would hear back from my recruiter. I heard nothing for a month, except the couple of times I reached out to my recruiter, who advised that they had heard nothing from the hiring managers, until over a month had lapsed. Then I received a generic rejection email with no feedback, which does not feel fair after my time and efforts.
