J.P. Morgan Software Engineer interview questions

I got to go into their Chicago office for a tour and a lunch. The interview was broken into four parts, behavioral, two technical, and a presentation of one of your projects. The technical questions were straight forward and nothing outside of any practice material online.

In first round around 30 small programs were there. Which covers all topics multithreading, collection, design pattern etc. Second round was F2F mainly focused on collection and design pattern
