BNP Paribas Data Scientist interview questions

Applied online through their site and was very quickly booked in for a technical phone interview the next week. The interview itself was moderately difficult, but was made worse by taking place over arguably the world's worst phoneline with an interviewer with relatively poor English skills (leading to a lot of confusion with regards to word meanings etc.) and an incredibly heavy accent. The questions themselves were relatively challenging but were made more difficult by the interviewer providing wrong information when asked for clarification, which he would then backtrack on a short while later (this happened multiple times). It honestly seemed a very amateur operation and I'd expect much better from a company as large as BNP Paribas.

I applied through a recruiter. In the first phase I did a logical test. Then I passed to the next round interviews. This round consisted of a 30 minute HR interview, a 60 min data analysis test, whose results I had to discuss in the following interview with the team manager. In this technical interview I was asked a couple of questions regarding programming and data analysis, and also ideas to represent data results (I believe where I failed the most). I didn't pass to the final round interviews (videoconference with some managers).
