MongoDB Sales Development Representative SDR interview questions

telephone screening from hr, manager interview(Virtual), assessment test, interview with sales manager again, his boss interview, competency test, situational test, offer. Got to teh competency test then they went with someone else

They reached out to me via LinkedIn. It was pretty swift, but I received a rejection email after the second interview with no specific reasons. Reached out but received no responses at all. Might be good not to join lol. Rejection isn't the issue, but completely ghosting candidates really isn't appreciated.
