Capco Senior Software Engineer interview questions

The technical interview was really poorly conducted. The interviewer wasn't clear and seemed unprepared. During the system design element, the interviewer wouldn't answer basic clarifying questions and kept interrupting me to basically repeat what I had said in slightly different words. I was then asked some questions about Java and spring boot. I have a transcript of my interview and I validated my answers afterwards which were clear and well explained but in my feedback they said there were gaps in my technical knowledge. One of the worst planned interviews I have had and I don't feel like it was designed to see the true capabilities of the candidates.
