I applied through college or university. I interviewed at Citadel (Chicago, IL) in Aug 2017
Interview
Recruiter reached out to me to schedule phone screen, phone screen question difficulty was slightly above average but nothing too crazy. They really want to grill you on your data structure/algorithms knowledge in order to see if you are a good fit.
Interview questions [1]
Question 1
Find the maximum amount of money you can make if you buy and sell stocks once in an array.
First did OA and only passed 1/2 questions, where the first one was probably a leetcode medium and the second one was an easy. Then got first round interview, which I havent done yet.

Question 1
1st OA questions was I think a search problem and 2nd OA question was a dp problem.
First round 45 mins total with short behavior and technical. I had one question, which was a class design question using heap. Solved question in time but did not hear back.
OA, one technical round, technical superday (3 interviews), leadership call rounds (mix of technical and behavioral qs, typically 2 ro more calls). did not pass the leadership round, very high variance.
