Hydropoint interview questions

I first had a phone screen that lasted 30-45 minutes going over my background, previous projects and some technical questions relating to the required language. I was then e-mailed that the phone screen went well and they would schedule me to come in for an in person interview soon. Nothing. I e-mail them back asking when we should schedule and finally over a month past the phone screen, an in person interview is scheduled. I attend the interview and I felt like everything went well. I could answer all the technical questions with ease. I was told I would be contacted soon for a second round of interviews with the dev team. And..... Nothing! Completely ghosted, even after following up over e-mail. Very unprofessional process and a complete waste of time.
