Stacked(Ireland) interview questions

I completed a phone screening interview at first. Then prepared a presentation that I gave during a second interview, including questions about the ideas I had in the presentation. I didn't receive any feedback on my application so I followed up with them. They said they would update me but I never heard from them again. I found it very disappointing considering I had prepared and given a presentation and taken two interviews, and they could not update me on my application.
