Extremely standard MBA associate interview process (technicals from the guide in phone screen / super day / offer). Generally the interviewers were friendly and the interviews were conversational. Super day in person.
I applied online. I interviewed at Jefferies (New York, NY) in Dec 2016
Interview
The process began with a phone screen that was done by an associate and an MD. This was followed up by a superday that included 3 interviews. Found out within a week that I had the offer.
