MongoDB Associate Pre-Sales Engineer interview questions

Started in February, 5 rounds. Got through the initial interview and it felt great. I did the technical evaluation and mock demo and they said it was a fantastic demo, they would be in touch with next steps. Two weeks went by so I emailed the recruiter and they confirmed I was still in the running. That was two weeks ago (from posting) they just ghosted me. All the listings closed and I can read the story from the posts here some one else got the position. I am fine with that, good for them, but its a bit of a bummer. I would have really liked to know what went happened.
