Autodesk Manager interview questions

Interviewer was late to the session, nor focus and somewhat inattentive to interviewee's responds to his qns (concise or short summary). Rather scoffing and insisting on my current package, expectation at early stage, when respectively deferred to discuss only at end/negotiation stage. Likely exceptional case in this instance.? Never have encountered similar case in other companies.

I reached out to an employee within my network to inquire about a job on the education team, and I had an interview set up right away. I spoke with the hiring manager and the HR representative that week, and set up a video interview for the following week. After the video interview, I was invited to an onsite interview for two weeks later. I felt that the interview went well and the questions were mostly behavioral and what I expected. I then had a follow-up video interview with one more person. At that point, I expected to hear within the next week or so what the hiring manager's decision was. I received an offer from another company, and so reached out to confirm Autodesk's decision, but I was told by HR that they didn't have a firm timeline and they couldn't get back to me before my other offer expired. At that point, I reached out to the hiring manager to ask for clarification, to which I never received a response. I never again heard from either HR or the hiring manager - my interview experience with Autodesk was initially positive, but the end was very negative. Not alerting a candidate who makes it to the final stages of the interview process that they did not receive the job is extremely unprofessional.
