Glassdoor Project Manager interview questions

I was intro'ed to a Director of Product Management by a friend, and luckily he was the hiring manager for the position I was most interested in. Had an initial screen call to cover my background, then an in-depth call to discuss ideas relating to Glassdoor. He then referred me to a VP for a second opinion, and that call was substantially harder as I think he was dubious about by background to start. My experience is largely in early stage startups and as an entrepreneur, and I had never worked at a later-state startup like Glassdoor. He asked for some work examples, which I sent, but it was not enough to convince him. It was frustrating because I believe the hiring manager wanted to hire me and I was enthusiastic about the role (and believe I was well-suited for it). After I received a somewhat boilerplate rejection, I asked the VP for some feedback as to why they passed. He was happy to answer: They were looking for a candidate with more high-traffic website experience.
