I applied online. The process took 5 days. I interviewed at Jane Street (London, England) in Jan 2022
Interview
The technical interview is a crucial part of the process and focuses on evaluating your quantitative skills, analytical abilities, and knowledge of financial markets. You can expect questions related to probability, statistics, mathematics, programming languages (such as Python or R), algorithmic trading strategies, and financial derivatives. Be prepared to solve quantitative problems, explain your approach, and demonstrate your understanding of trading concepts.
I was qualified for the first round of the interview proccess. I was asked about the reasons why i want to become a Quant and why i applied in Jane street for this role. After I was asked two probability questions. The interviewer was ok but at some moments I wasn't sure if she was following my thoughts

Question 1
Mainly I failied since I tried to give them a strict answer to one of the problems(which was impossible to calculate in this time) and the wanted to hear some intuitive approach which leads to approximately correct answer.
they spend a lot of time trying to understand your thought process. the interview question use simple scenarios and build from them to more complex ones to understand how you handle adversity
