Yes, I was lucky enough to be offered a position. The first round interviews were literally just two interviews with two different senior members of the division, back to back. Competency based, not much more to it than that except that they will ask you an analytical question like “how many panes of glass are there in this building” etc. You can’t prep for something like that so make sure when you answer it to start with all of your assumptions and build your answer around them. Just like you would a maths equation.
Apart from your competencies make sure you know about the firm like who their competitors are, what makes them different (opportunities/global reach etc), learn stuff like which areas of the globe they offer their services to and how they vary. If that information’s not available in any way, use it as a question at the end to show you’re genuinely interested in the job, not just the name/money. That’s what they want to see.
I’d recommend learning in as much detail as you can 2 or 3 products/services JPM provide and what they do. Try and drop the knowledge gained from your research into your answers to make them see you’ve done the work.
Apart from that, read the news! I was asked about a recent piece of news (which at the time, the whole US tapering quantitive easing was a hot topic). My interviewer rolled her eyes as clearly she’d heard it all day, so I went on to talk about how the US markets affect China, long term/short term, and how the Chinese had just released the ban on IPO’s and what that will infer to investors and the markets, not just in China but globally. Also, how JPM are affected by it all etc. This was especially relevant as the Treasury services division I was applying to manage cash flows/working capital…so you may not need to know something as in depth as this but the point is to know maybe two pieces of solid business news and how JPM and your division are affected by it.
Good luck! I hope this helps, let me know how you get on
