I took a quantitative analysis test that contains questions relating to Maths, general knoweledge of coding, but mostly time complexity and code efficiency. It was not too difficult, but you should definitely prepare well. The questions are technical and requires proper knowledge of the subject

Invitation to technical assessment with 3 parts, core, derivatives, algos. One was on common math/probability problems that one might expect (e.g dice rolling), one on options pricing, another were common coding problems + ML questions
