I learned about the job listing through campus recruiting. The interview was a 30-minute interview focused on personality / fit rather than technical / finance knowledge. I was interviewed by two executives from JPMorgan: one from corporate and the other from human resources. The interview was pleasant overall; but there were some questions that were quite challenging, e.g. my views on the state of the economy, potential business growth opportunities for the company, etc.
The people I met with came across as intelligent and driven, with high expectations from their colleagues. I imagine the work environment to be intellectually challenging with opportunities to learn about different aspects of the business.
