Fake Job postings, no response after the HR call. Just had the call with HR, and HR mentioned he is waiting to hear back from manager but no response after that

3 rounds interviews for me. The first round was HR rep who didn't make an appointment but called directly, that I thought it was a bogus call and luckily I picked up the phone at last. The second and third round were hiring manager. He was very friendly and nice. Mainly asked about my background and history, and then he shared a lot on projects handled by his team, challenges, and also his expectations. The interviews went very smoothly.
