I applied online. I interviewed at Jefferies in Oct 2019
Interview
Phone screen, basic behavioral questions, market opinions, what do you know about the role, then the interviewer told me about the company, the position, the business they are doing right now.
I applied through college or university. The process took 5 days. I interviewed at Jefferies (New York, NY) in Apr 2015
Interview
Got one phone interview for 15-min and the manager invited me to their Super day during the following week. During the onsite I interviewed with 6 managers, while two rounds are behavioral and situaltional problems, and one round is pure statistics.
