Euromonitor interview questions

Had stage one of the interview after they cancelled twice. Was told i got through to the next stage but then got ghosted. No communication from the company at all.

I applied online and was invited to speak to HR a couple of days later. I spoke to a nice lady who was really knowledgeable about the role. She told me she would speak to the hiring manager as I seemed like a good fit however, I waited about 2 weeks to hear back. I sent an email during this time but I didn't get an acknowledgement or a reason for why they were taking so long. Once I heard back, I was asked to complete a task, there wasn't much context given apart from create an email marketing campaign. I completed the task but didn't received a response after a week had passed so I followed up with an email. The next day I heard back with a response that they weren't moving forward with my application and the feedback that was given was very generic. I responded and asked if I would be able to get more detailed feedback to which the lady in HR said she would ask for more. 2 weeks later and I haven't had a response. The task was also given before the interview so I never actually got to that stage of the process.
