Phone interview of 45 mn. Of you suceed then you are invited to the assessment centre on their site. Applied online and via an offer given to my MSc. I was asked to present myself, my experiences, my cv then just few probabilities questions with hard ones. I didn't get an offer for the second step.

I first applied online for the quant trader position. After resume review, I got emailed a link to a one hour online assessment about machine learning algorithms and some other math problems. Following that, I was scheduled for a technical phone screen with probability problems and some mental math.
