I applied online. I interviewed at Citadel (New York, NY) in Nov 2023
Interview
Step 1: OA - coding challenge in HacherRank,
Step 2: First round tech and behavioral interview (45 minutes) , and then
Step 3: Three Virtual On Site interviews (45 minutes per interview).
Got an rejected email 2 weeks after Step 3.
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.
Interview questions [1]
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.
