Barclays Business Analyst interview questions

I interviewed at Barclays(NY) in October 2021 for the role of Business Analyst. I applied online and the same day recruiter reached out to me saying they really liked my profile so it was a brief overview of my background. The next round was with the Hiring Manager and she was fun and easy to talk to. I got the invitation for the next round in a week and was asked to share my availability. After providing the dates the interviewer rescheduled for 4 times and it was always on the day of the interview saying he was busy or out of office. This was the worst professional behavior I expect from such a company. Finally, I interviewed with the person in Mid-November and he said they would reach out in a week. After 2 weeks I reached out but there was no response from the recruiter and in late December just before the holidays the recruiter reached out saying they hired an internal candidate.
