I had a phone interview with the HR department first and got invited to interview at their office. I had 3 interviews back to back. The first was a 2:1, followed by a 1:1, and the another 2:1.
They ask me about my resume, lots of technical questions, and questions about the company. In the last interview I also got ask a brainteaser question, which I luckily answered correctly.
To be honest I didn't really like the atmosphere at Morgan Stanley so I am not upset not to get an offer. Once I left the building that day I knew I didn't want it anyways.
