CrowdStrike Internal Tools Software Developer interview questions

Super odd - recruiter reached out on LinkedIn, had an HR call and then interview with hiring manager. We discussed my job experiences, dove into some projects a bit, some scoping questions about high level security knowledge. It was a positive experience and the manager was intelligent and empathetic. At the end of the call they said I'd hear from HR about next steps, then I was just ghosted entirely. I don't know if I didn't really communicate enough of an interest, since I already had another offer lined up but yeah, bit odd to have been ghosted even though it was indicated that next steps would be happening.
