Zilo Technology interview questions

The most unorganised company. I had to chase up for a confirmation for the first round. The HR manager was nice and warm. I managed to pass this round which was just a conversation based on my experience and what the job entails. The second round consisted of a presentation about yourself. I was on a call with the another member who was based on another company. He did not look interested and didn't say goodbye. I was told I will be updated regardless of the outcome. However, I was ghosted and I even I sent an email to follow up. Zilo need to be more emphatic that it takes a lot of time and emotions to prepare for an interview. The amount to time to create a presentation and to present this and then not to bother contacting the candidate is unprofessional and unkind.
