Microsoft Senior Software Engineer interview questions

Had an initial technical screen followed by a virtual onsite. A few days later I got an email from a business recruiter that Microsoft had an offer for me and requested availability to discuss the offer. After I sent the availability they did not reply to any of my emails for two weeks. After that they sent me an email that all positions were filled and they are sorry. I reached out to the talent sourcer and they said I had cleared the interview but all positions were filled before they got to me. Then they completely ghosted me. I did not expect this from a company like Microsoft.
