BNP Paribas interview questions

It was a scheduled interview. It started as per schedule and first round was face to face technical interview. The interview went on for more than 45 minutes. I was told to wait in the same room and a managerial round was taken for about an hour. Then I was told to wait in the lobby till the next instruction is dropped by. I was asked to come in and it was my mindset, it would be an HR round like other companies. But it was again a technical face to face round which went more than 30 mins. Questions were quite tricky and not upto average 2 year experienced interview questions. After about 2 and a half hour of face to face technical interview, a candidate is prone to stop thinking technically and his analytical power is going to get down. I would have suggested if the rounds were taken on different days. Or they would have some technical written test so that candidate's energy is saved and he gives his/her best.

I applied online, got tests and then invited to the AC in the CIB hq, London. Three rounds, 1 math test 2 exchange rate test and 3 1-1 interview with another analyst
