I got contacted by the founder as someone is leaving the role. The interview was interesting but i didn't make it. The founder just chatted a lot about the founding story of the firm

There was a screening round, a case study, and a more in-depth interview based on the case study responses. Interviewer was more interesting in proving he was smarter and more capable than me. Took a very adversarial and confrontational approach. Later, the interview feedback given to me was, I didn't know my work. It was odd, because interviewer was from a different background than me and had less years of working experience. Interviewer was also frank about their goals: that they were still shopping and might not hire anyone at this point.
