The process was relatively straightforward. First a HireVue, followed by a basic phone call interview about interests/my resume. Then a super day with 4 interviews. Everyone was really nice and friendly.
The HireVue and phone interviews were pretty straightforward. Definitely study. The Superday math questions were tricky - they were a mix of probability and brain teasers. I don't know how they want us to prepare for those but would definitely recommend taking a statistics class.
I applied through college or university. I interviewed at Morgan Stanley (New York, NY) in Aug 2018
Interview
There was one phone interview screening and then a superday. The superday consisted of four thirty minute interviews and was a mix of behavioral, markets knowledge, brain teaser, and general questions. Must know your story and why MS / Fixed Income / what product you are interested in.
