Envision Healthcare Sysyem Engineer interview questions

I had a 2 hour interview with 4 team members. After the interview I was told things went well and was even given a tour of the place . Once it concluded, I politely asked the hiring manager to let me know when a decision had been made and to let me know if I made it or not. He promised that I would hear back within a week or two on the final decision. Well it was 5 weeks later and I did not hear back after multiple followup attempts. Not even a hey thanks for your interest but we chose someone else or the position was out on hold or at least email me. I'm shocked at the lack of professionalism. I'm taking my talents elsewhere. Complete waste of time.
