The entire process took around 4 weeks. There was 1 round of interview on campus, 1 group activity and other 3 rounds of interview at Morgan Stanley office in NY. The group activity was fun, they mostly check how you approach a give problem. The technical rounds will focus mostly on what you mention in your resume. They touched upon almost all the languages I had written in my resume and tested the breadth of my knowledge (not so much the depth). My primary language was C, so they asked me to write few codes in C. They also asked me to write few Java , HTML and CSS code and SQL queries (although they were quite simple) as I had mentioned them in my resume.
