Easol interview questions

Standard interview process: TA, manager, task and culture fit. All went pretty quickly, the process was wrapped up in 3 weeks. I really enjoyed all conversations I had, everyone was very nice and easy to talk to. I received positive feedback at the end of the process and was asked to wait and stay close. Just to get ghosted. I've never heard back from them which taken that I went through all stages, prepared a presentation and was hinted that it's going to be a positive outcome, it's unacceptable.
