iHeartMedia Software Engineer interview questions

Recruiter reached out to me about an interview and immediately ghosted with no explanation. I'd prefer careful consideration before reach out or a reason why the interview process ended ended.

(1) HR Phone Screen - simple, basic, what you'd expect from any HR phone screen. (2) Interview with SVP of Engineering - conversational, basically talking about the project they're working on and what my place would be in it. Very nice guy, has been in the industry for a while and knew his stuff. (3) Interview with two team members - one was similarly conversational, the other was more technical-minded and asked a lot of questions about my previous projects. This was the one that I felt I didn't do well on, but still felt like I answered his questions satisfactorily judging by his tone. ... and then nothing for 2.5 weeks. I reached out for contact but haven't heard anything back. I assume I've been ghosted. If that's the case, extremely unprofessional and frustrating. (4) ... Ghosted!
