Perguntas de entrevista de vagas de Solutions Developer da empresa InterSystems

I interviewed for the SDP. 3 OAs very unique and annoying. One of them was like the SAT. One phone call and five 45-minutes interviews. All of these interviews were mostly behavioral. Some of them had technical questions. It's really about the interviewer's choice. I have put so much effort into the process and I thought I did well but they rejected me. They don't have any obvious criteria and the interview process is soul consuming. And for what? 5 days in-office job with dress code and weird tech stack?
