Applied through their career website. The process took about 2 months. I interviewed at Morgan Stanley (New York City) in September 2018. They covered all traveling expenses and booked a hotel room. Once on the site, there were other candidates and a small panel from HR and technology department. After the panel, we headed to a big open room where we were interviewed individually by technology department employees. There were not many behavioral questions, many were technical questions. Waited 2 weeks for a response. Other candidates had it easier with no technical questions asked. In the end, it really depended on who was interviewing you.
