Pretty easy and not that hard. Mostly based on my resume and it wasn't such that it wasn't hard but it wasn't that easy as well and you'll be able to handle it pretty easily
first HireVue, then Superday, 3 interviews and one math test. Math test contained statistic and probability questions, classics from the the green book. Took 2 weeks between Hiruevue and super day, then 2 more weeks until recived offer.
Campus interview - asked questions about interest in following market trends, ran through case studies of a couple companies in a sector, discussed impact of geopolitical events to businesses, and some basic accounting questions. Then discussed long term goals and reason for interest in the space.
Asked abt markets. Hobbies. Rates. Asset allocation. Background, why I want the job, why JPMorgan, time when I faced difficult decision, typical behavioral questions not anything super crazy outlandish. Good luck
