For the first step, I got pinged by a recruiter. When I told them I wasn't quite sure about their culture, the engineering manager wanted to directly talk to me, so I figured they had some interest. I setup the phone screen, and passed. I went to the next onsite interview which had 3 technical rounds which seemed to go ok. (One made mistakes in his responses to my comments, but I didn't say anything.)
Second onsite involved the HR, which was focused about how well I understood their culture deck, etc. Right after that, I met with the VP, who more or less took a complete 180 of their culture deck. He didn't believe in paying people what their worth (the whole baseball analogy that their culture deck pointed out). Mentioning that I was still interviewing elsewhere in case this didn't work out seemed to be a mistake, something HR and the VP brought up multiple times, although this contradicted their culture deck. He also mentioned tons of bureaucratic rules and regulations that were again, something the culture deck was trying to say made them different from companies like IBM, Apple, etc., but he more or less up front said they're the same.
I figured since I love working on projects on the side that do not compete with the business, and constantly look for outside the box solutions that working on side projects bring, it would be a good fit culturally, but I guess I was wrong.
