3interviews, one HR interview, one manager interview, one COO interview. Manager interview is decisive. COO interview is more casual and more about behavioral questions. HR is more about your personality and your salary expectation.
I applied online. I interviewed at BNP Paribas in Jan 2019
Interview
The interview process was made to be very relaxed. There were a lot of technical questions ask and were geared towards what the job would be about. The manager interviewing was definitely knowledgeable and knew exactly what he was looking for and didn't make you feel "little" if you didn't know the answer.
