Alior Bank Java Developer interview questions

I applied online. I got a quick email and was invited to technical interview. I went to the office and met with 2 people who would ask me technical questions and told me a bit about working there. There were rather nice. The questions where mostly easy but I got problems with written code - they really like those questions about the outcome and what would happen when you change this or that. Totally useless in normal work but very common during interviews unfortunately. They never answered me after the interview and it's been over 3 weeks. I wrote them an email asking if there is another part of the process but they wouldn't even answer. Very rude of them.
