I was called to interview for many positions at J.P. Morgan. I was actually a bit overwhelmed. I met with many groups interviewing. Some of the groups were okay at interviewing. Others asked non-technical questions through the whole interview, and I found it to be a complete waste of time. I don't think I will ever interview at this company again. Also, you will barely receive any feedback from the coordinators.

I was asked to do some probability problem, calculating the probability of rolling a number. The maximum subarray problem, the interviewer was looking for an N^2 solution, while I was trying to explain the n log(n) solution.
