Application through careers website, was invited straight to final round interview five weeks later. Had the barebones of a case to prepare that we were given more information about on the day. Assessment center took place at JP Morgan's building in Canary Wharf.
Day was structured around three interviews - first we were given two hours to go through the case and write our recommendations in a word document on a laptop. Following this we had a role play situation in which we pretended to be a junior analyst who had to present their findings to a JP Morgan Associate who was role playing they had a more senior role. Very intense with the employees clearly having been instructed to play the part of the demanding client.
After a break, two more interviews that were more based on evaluating experience, personality and competencies. Much more relaxed tone and pace relative to the other two.
