Intercontinental Exchange Risk Analyst interview questions

Received an email from HR regarding the position, then arranged a call with HR. HR explained the process and went through some basic questions regarding salary expectations and skills. Then received an email from HR regarding times and dates for a 1st stage interview. Interview took place over 30 minutes, was very unprofessional. Person interviewing me was wearing a hoodie and clearly had not prepared at all for the interview. He then proceeded to ask random questions from my CV on the fly. I felt the interview was rushed and that they may be interviewing just to show numbers, while having selected an internal candidate. I was well qualified for the job. I then receive no reply from HR regarding the outcome, I contact HR to find out I have been rejected. I would not recommend you interview with this company, as they do not value your time and do not prepare for interviews themselves. I was also told there are several stages in the interview process, at least 3, so do you really want to waste time with these time wasters?

The interview was two rounds. HR round and technical round. Mostly on statistics and mathematics. They test if you know the concepts well. So, it's mostly on the technical knowledge, and if you are strong in statistics, you will get the job
