Ask HN: What is required of a Product Manager?

Hello, I'm having an 2nd interview for a junior/mid-level Product manager position on Monday in a kinda web agency / Startup. This interview will be focused on the "product management theory". About me: - I have a bachelor and master degree in business & marketing. - I have worked the past 4 years in marketing - I learned to code ( python, js, html, css & co ) on my own the last 6 months and I can hack a prototype. - I know my way around photoshops, premiere, indesign. - I have a deep knowledge of the web industry since It has always been my passion. - At my previous jobs we used scrum methodology and I have a good understanding of it. I have never been the Scrum master though. This position is the next level for me. I have been a marketing manager or in charge of something marketing related ( SEO, emailing, PPC, etc ) before but never in the "product team" but this is kinda what I would want to do for a living going forward. So What kind of questions do you think they will ask me? How can I prepare myself to this interview? PS: english is not my 1st language so don't just me on my spelling ;)
