I am obviously not a native speaker and I probably don't really get what the manager round interview is about, but it would still assume that it's not about QlikView, but more about 'soft skills', right?
If so, any of the above referenced sites should get you an idea what the topics will be.
It is very hard for me to improvise and quickly respond to questions, so the answers to them take a very long time. That is why preparing for an interview in a new workplace sometimes takes weeks for me. I study the structure of the company, trying to understand what questions HR can ask. Last time I even ordered a resume from resumeble because I really wanted this job and wanted to eliminate any mistakes to make my resume perfect. So thank you for the questions. Now I will be ready for anything.
