I applied online. The process took 1 day. I interviewed at J.P. Morgan (London, England) in Nov 2013
Interview
I applied online and was invited to schedule a first round telephone interview. It lasted for forty five minutes. The questions were mainly technical: brainteasers, probability questions, stochastic calculus, numerical methods, integrals and programming.
The probability questions were fairly simple, dice problems mainly. I found the integrals and programming questions a bit more challenging.
Interview questions [1]
Question 1
There was a question about a change of variable in a multiple integral. Don't forget about the Jacobian.
