Nokia Java Software Developer interview questions

Firstly HR recruiter called to me one day after my application. She asked me about my salary preferences and time availability for working. Then I got a link with very easy coding assignments. Finally I had a interview in Nokia. Recruiters asked about a lot of details from Java, Python, it surprised me, because I was applying for a Java Developer, but I had a mention about Python in my CV. I had to write a code of their computer. I was very disappointed about very detailed questions about Linux, Git, Spring and others which some of them I had never worked before.
