Gleamer interview questions

The process was smooth and very nice up until the end. I had an HR interview , then I met with the head of marketing. Everyone was lovely and the interviews were simple. I then presented my case study and was ghosted for 3 weeks. They finally came back to me and told me they wanted to move me to the final round. They scheduled the interview then they rescheduled and then in the end cancelled last minute because the person I was meeting had something else last minute. I was then ghosted again. This company lacks serious communication skills.
