ecobee Technical Support Representative interview questions

SUPER UNPROFESSIONAL I applied for the above position and after reviewing application they invited me for the phone interview. On the day of phone interview, I received the call from the same person who wrote emails earlier. The very first thing he tells me is, "Hi there, Sorry to tell you that there has been some changes to the Job's Requirements and we'll have to reschedule the call till next time". And I asked him, "What kind of changes, can you please tell me more", and he said he'll write email in detail and that he will have to end call now. Now after two days of waiting, I never received any email. So I wrote email for the follow up and this as well never received any response. And after probably couple of months, I received email that sorry about all that but there were some change and because of that they couldn't move my application further. SUPER UNPROFESSIONAL, IF YOU CAN FIND A COMPANY WHO CARES ABOUT PEOPLE AND ARE SOME WHAT PROFESSIONAL!!
