I applied through college or university. The process took 1 week. I interviewed at J.P. Morgan in Feb 2011
Interview
Applied through University Recruitment Portal, and was called up for an interview. The interview went through 2 stages, both roughly the same. They mainly asked behavioural questions, and a few minor technical questions. Overall was a typical interview process.
The process took 3 days. I interviewed at J.P. Morgan in Jan 2012
Interview
2 interviewers. One asked more about related experience/interests, as well as personality questions. The other asked some generic technical questions (pretty easy ones about OO, etc.). Would have been pretty easy, but one interviewer cut me off a few times, which annoyed me. A few days later, I heard that I did not make it to the next round.
