I applied through a recruiter. The process took 2 weeks. I interviewed at Citadel (Chicago, IL) in Dec 2016
Interview
An onsite interview in Chicago. It was a very pleasant experience, with four rounds of coding and technical interviews. The interviewers are all very friendly. The difficulty of the questions vary a lot, but the questions are all quite interesting.
Interview questions [1]
Question 1
Standard questions about data structures and algorithms
Online assessment with 3 coding questions on bfs and stacks etc.
First round on a simple coding question with some basic CS questions on top of it and also asked many CV questions and motivations
Did not proceed after this round
OA then phone interview, discussed about experience, coding rounds, and some open ended questions afterwards. The last 5 - 10 mins was for interviewee to ask questions back. Didn't pass this round :(
I had an HR screen where they asked about my experience at my previous company and to prepare for C++ to talk with the hiring manager. They asked about why I got laid off at my previous company.
