Glassdoor 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.

The overall process was SO long - about 6-8 weeks, from the time of "we want to bring you in" to the final interview. I wasn't in a hurry (I had a job) but still, a little excessive. It started with a phone interview for chemistry check with the hiring manager, then went to in-person meetings with the entire team. This was for a senior level position so all was expected -- except, I found some of the questions and the tone of the interviewers to be patronizing (as in, "that's right, that IS what you'd do!") ... I'd say that "patronizing" was the tone of the overall process. After the initial in-person, I was asked to come back to give a 15-min presentation about myself. Ok, I can go with that, but had my suspicions about it. I'm interviewing for a senior level position... don't you want to know more about how I'd handle difficult situations applicable to the job description, or how I'd approach things from a strategic perspective? Sure, I'll tell you what I like to do in my spare time (a cultural fit is as important to me as it should be to the company), but to answer the question "Why should Glassdoor be excited about me?" in PowerPoint form? I was already feeling this wasn't a cultural fit. After I presented to a larger group of folks, they asked me to wait in an empty room for 20 minutes. Nothing to read, no water offered. Just... wait here, we won't be long. Thankfully I had my phone on me for something to do. After all this, I received an email with one sentence, "Sorry, we decided you're not a fit." No explanation beyond that. After this whole process, I'm of the impression that the more professional thing to do would be to provide a more polite and friendly email (something to the tune of "while we liked your skillset, we're looking for someone more xyz."). As excited as I was about the prospect of working for Glassdoor, the interview process left a bad taste in my mouth - and it truly isn't because I didn't get hired. Meh.
