The first round interview was done in the following process:
1. Enter Bloomberg building and get invited to a meeting room.
2. The HR lady explained about the company, working culture, the role and its career path. Successful candidate will be provided training for about 8 weeks, take a few exams. After that, you would become a generalist and work in the Analytic team for a while. Then, you will again receive training from Bloomberg. If successful, you can choose to be a Team Leader in Analytic team, Financial Sales, or Advanced Specialist. This is the career path they suggested.
3. After explanation, you will be asked to give a brief self-introduction and tell them why you are interested in Bloomberg and apply this position.
4. Then, candidates will be divided into groups. A (role-play) scenario with a task will be assigned to each group. The group is expected to give a group presentation, try to convince the other HR lady (who will try to give you a tough time) and complete the task as specified. The HR will observe your communication skills and determine whether you are shortlisted.
I was shortlisted. However, I didn't want to go to second round interview. From the phone, I was told a team leader/manager in the Analytic team will attend the second round interview and they really want the candidates have passion about Bloomberg and the positions they applied.
