Altium Limited Content Developer interview questions

I interviewed for the position in July and have not heard back since the end of October. I received a phone call about the position today requesting a call back to discuss the role. After speaking with the recruiter about the interview in July they just told me the position was filled today. Why bother requesting to speak over the phone to let me know it was filled 3 months after the interview?

Had a screening with a recruiter and I thought went really well. He was very kind and easy to talk to. He said I seemed like a good fit, and would schedule an interview with the hiring manager by the end of the day. When I asked for this person's name, he was vague and wouldn't tell me his name. He also never asked about my salary expectations, and called 15 minutes later than what was scheduled, stating that my phone number was typed wrong in his computer system, even though it was written correctly in the interview confirmation email, as well as on my resume. He said I would hear back within in 24-48hrs, but one week later, I get a rejection email saying they decided not to move forward.
