Applied with a recruiter, and company came back with a response in a day or 2. The interview was very casual and relaxed. It felt like they were already feeling good about me based on resume, and wanted to make sure I knew everything I needed to about their company. There was no whiteboard coding or personality riddles. There were general questions about my exp in past roles and with certain technologies. Plenty of time for you to ask them questions. Interview was in 2 parts, one with the tech leadership, and the next with the co-CEOs. No offer since the company and I were on different wavelengths on some things. But everyone I talked to there was incredibly nice and easy to have a conversation with, and it seems like it would be a good place to work.
