Zenitech interview questions

I had a 1 hour long call with HR at first. It was an okay experience, altough they were pushing for more information about the project I'm working on at my current company. While I understand that they try to determine if my experience fits their expectations, they should also understand that developers are generally not allowed to fully describe their projects. At the end they promised to get back to me before the end of that week. They didn't, I heard from them around the middle of the next one, which can still be considered ok. Then I had a technical interview, where I actually had a positive experience. It was a hour talk about my experience, the tools I worked with, and how I solved some challenges in the past. At the end, again, they promised to get back to me. This was all a couple weeks before Christmas. After waiting for an answer or feedback for over a week, I sent a follow-up asking if they have any answer. The HR told me she will get back to me next week and she's sorry for being late. They didn't reply before Christmas, which actually gave me the reply that they don't want me. I sent another email in January telling them that at this level, after two long interviews, applicants deserve an answer, whether it's yes or no. Of course they never replied, but this says everything about them. It should not be allowed to treat applicants this way.
