I applied online. The process took 5 days. I interviewed at Jane Street (London, England) in Nov 2018
Interview
Few technical questions on the phone, no paper and pen allowed which makes it harder obviously. The interviewer expects you to answer very quickly, if not you will be rejected.
Went through 3 rounds of interview, all of which were focused on math. they started with basic questions and built up to harder ones. Also some behavioral questioins at the start of each round
Applied online and passed the resume screen, got invited to a first round, didn't pass, was my first time interviewing for quant and nerves made me answer not quite at the best of my ability
