I applied online. The process took 4 months. I interviewed at BNP Paribas (Londres, Angleterre) in Feb 2018
Interview
Oline process was very wasy. Answered a few questions on their website and then was asked to complete some online tests, followed by an online interview. The process was very smooth and eve though I didn't have a very good knowledge of markets I managed to go through the process easyly. I recommend reading the financial times/bloomberg a few days befire taking the online interview.
