A couple of the interviewers were nice, a couple were rather cold. Overall, the coding questions contained nothing particularly challenging (although not that it was easy, just more that it was pretty much what you would expect).
Interview questions [1]
Question 1
They asked some questions about pandas/numpy operations.
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
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.
Application
I interviewed at Citadel (Hong Kong)
Interview
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 :(
