I applied online. The process took 3 months. I interviewed at J.P. Morgan (London, England) in Feb 2017
Interview
2 round of telephone interviews, followed by a superday. Each telephone interview usually quickly go through CV and then 4 or 5 tech questions. Telephone interview cover a lot of maths like markov chain, stochastic calculus, probability, statistics, not go into very deep. Usually get 3 questions well answered can give a good chance to pass. On superday, 1 on 1 interview with several interviewers. Questions are similar to telephone round but much more difficult. Little time to take a breath between meeting different interviewers.
Interview questions [1]
Question 1
Great focus on stochastic calculus questions, such as brownian motion, martingale, application of ito lemma. (Whether W^3 is a martingale or not, if not, add a term and makes it a martingale). Markov chain (2 people play a game, roll the dice one by one, the person who first roll the 6 win, what is the probability of the 1st person to win). Some probability and statistics questions. A little linear algebra.
3/5 questions are maths, 1/5 questions are coding (such as the inheritage of the class in C++), 1/5 are financial questions(delta hedging, butterfly option spread).

Interview
I interviewed for the position of Quantitative Research Associate for three different desks at JPM. The HR/recruiting teams for each of these groups did not communicate well with themselves internally. In total I had 6 interviews with the wholesale credit team, 2 with their RAAS group, and 1 with their rates desk.
Eventually, I received an offer from their wholesale credit team for what I believed was a below market offer. When I attempted to negotiate, they came back saying this was the most they can do, and I walked away.

Question 1
Standard Python programming, statistics, and probability questions that you are expected to know for this level
What is a decorator and how is it used?
Describe basic data structures and their uses.
Describe how importance sampling works.
I took an online assessment: two codings questions plus one written exam. preparation for a week or two. Suggest leetcode to practice. Very long waiting period for phone interviews.
