CACIB Internship interview questions

After applying I was asked to complete an online aptitude test. A few weeks later I had an interview with two partners who were extremely kind and supporting. I was also told that only four people have made it to that round of interviews and there would be another one later (if the first interview is successful) with HR. I was later informed hat I have been shortlisted for the job and that the second interview would be soon. But the date for the second interview was never set, and after repeatedly e-mailing and calling them I was just told that the hiring process was suspended because the HR person responsible for this role was out of the office, but I was assured that noone has been hired yet. Later I was informed in an e-mail (between Christmas and NYE) that they have hired someone else and they are not giving any feedback due to the volume of applications, even though only 4 people have made it to the first interview and I must assume the number of people (or person) shortlisted was even less. Overall, the interview was very nice, but the quality of communication after was unprofessional and not straightforward.
