J.P. Morgan Quantitative Researcher interview questions

Pretty chilled out. Asked from CV. C++ Python OOPs, Maths questions from probability, expectations, Random Variables, Random Processes, algorithms (linked list, arrays, recursion, binary search). They asked to explain your experience in CV, asked ML related question because I had done ML research before, HR round was very easy they just asked why you want to join the company and is relocation a problem etc

45mins phone interview directly with QR members. No HR phone screening. Apply online, receive interview request 3 weeks after. Presumably there are three more interview rounds to get into super day. No call back after.
