First round with HR, second round with 4 people (2 directors and 2 associates), and a final round. Interview process was rather untraditional because final round was only an hour long. There is a drug test and background screening before Natixis would extend an offer.

Got selected for their technical test though didnt get selected for interview. Had 2 days to complete the test, cannot disclose further sorry. Not sure why I didnt pass the test though.
