Several steps on interviewing, first a call with a recruiter, than a couple of more technical chats with senior engineers and CTO. Recruiter was nice, knowledgeable and overall communicated well. Senior engineers were quite unhelpful and overall disorganized and uninterested. CTO very switched on and interesting conversation. Overall rejected with some wishy-washy reasons - sounded very much like gatekeeping from senior engineers. Overall got a bad vibe, feels like there are people in the development team that do not want to relinquish ownership of quality processes.
