Minerva Networks interview questions

I had a video call with the recruiter, I wasn't expecting technical questions, but she shared me a word document with some Java questions in which I had to write my answers, there were like 20 questions. Onsite: * 2 engineers: some technical questions about Java, solved some problems on the whiteboard. * Tech manager: gave me a paper sheet with some Java questions and some algorithms problems. She was on the phone the whole time, she seemed very disinterested in the interview. * Manager: talked about previous experience, talked about the company. * Hiring manager: talked about my previous experience, about the company, tried to convinced me to work there. After some days, I received an offer with less salary than my current salary at that time. I declined it.
