HARMAN Cloud & DevOps Architect interview questions

Worst. After completing 2 rounds of interview, they scheduled 3rd round. And they said 3rd round will be rescheduled as panel is not available on previously scheduled time. I said ok fine. HR never came back with no communication at all. I asked on linkedin, and HR said business requirement is cancelled. I said Wow and you dint bother to notify atleast. Wasted my 2 hr 30 mins of my life in interview with Harman. I am pretty sure they would have gone for low budget resource, ok fine i understand business then why did you schedule 3rd round? Harman was not at professional. Will never apply for this company
