Diageo Business Development Manager interview questions

I applied for the BDM role for Diageo Perth. I received a one way video interview invitation. That was a red flag to me but I still did it. Very easy questions and I received an email saying in person interviews would be set up within the week. Two months later, no information. I sent an email within that time frame to ask about my candidacy. The hiring manager couldn't even be bothered to reply which made me think they hired an internal candidate and only put up the advert due to corporate obligation to show they're equal opportunity. After two full months I received an automated reply saying I was rejected. This company is very impersonal and out of touch--not even a phone call to screen their applicants.
