Siemens Commercial Project Manager interview questions

This was an interview for one of Siemens' regional arms, called SD Middle East LLC. The assistant to the HR manager called me to arrange an interview. Upon arriving at the interview, I started with a general interview (review of CV with general experience related questions) with the assistant who had arranged the interview. This lasted for 15-20 minutes. I was then told to wait in the waiting area after the assistant had found that the HR Manager was not available to interview me for an unknown reason (according to the assistant). After waiting for about 30 minutes, the HR assistant then proceeded to take me to interview with the line manager for Commercial Project Manager role, which was unexpected and unscheduled for the manager and myself. The line manager again reviewed my profile and asked general questions which were neither technical nor specific to the job. The HR assistant then explained to me that they would revert back to me within the month of January. I never heard from her regardless of NUMEROUS emails and phone calls. Finally, after about 60 days, I managed to get a hold of the HR assistant, where she gave me an answer she very evidently had improvised on the spot, explaining that the position had 'gone cold' (even though the line manager had explained during the initial interview that he needed the role filled by end of Q2 2017 and the interview did not consist of any technical portion to assess my skills related to the role). I then reached out to the line manager directly, and after failing to reach him after the first few emails and calls, I finally managed to reach him where he angrily answered the phone and explained to me that he 'wasnt convinced by my profile'. An answer that was not at all consistent with the answer given to me by the HR assistant. Overall the process was incredibly disorganized, incongruous, and demonstrated a clear lack of organization within their operation.
