1st round phone interview with HR, she was nice and friendly. Ran through your resume, and asked some basic questions such as why Bloomberg? What do you know about Bloomberg? Any interesting financial news recently? Do you have some machine learning experience etc.

One round of phone interview for about 30 mins asking about your background with a few technical questions relating to your expertise. Then the second round in person interview with 6 people. The entire process took about 3 hours and it was a little intense and at some point got repetitive as the interviewers took turns and asked the same questions unavoidably.
