BNP Paribas interview questions

First round involved a hackerrank test (which included a strict warning that if I don't attempt it I can be blocked for an entire year). The test was good and easy to crack. Second round was technical. This was a good experience as the interviewer grilled me on questions ranging from java, spring, hibernate, angular, JavaScript. It was a delightful experience. Third round was F2F at their office. This was by far the most unprofessional and confused company I have gone for an interview. They called me down for an interview, only for the interviewer to be out of office in another location. They took an hour to set up the video conference room. Post that the interview began. The interview was a good process, where some I could answer and some I couldn't. The problem started post that. The assistant of the interviewer told my feedback was good. The HR called up and was CONFUSED about my feedback and asked me to stay back. After staying back for 20 mins, he called up to ask if I could stay back another hour to schedule an interview with another team. I rejected as I had to go to office. Expecting his call later in the week, the next day I get a rejection mail. Why was the feedback received as positive when they were unhappy?
