Application

I applied through a recruiter. I interviewed at Citadel (Chicago, IL) in Oct 2020

Interview

Applied through a recruiter. Had a non-technical interview with hr. Then one phone interview consisted of cv review and three technical questions. Got invited to the virtual onsite. The first interviewer came half an hour late and we couldn't understand each other, as if we are from different planets. Starts questioning on details of my project (He is actually famous for being crazy so you should hope, he doesn't interview you.). The second interview of the onsite went well, it was some regression question and a LC type problem. After that hr called me that there is an emergency and rest of my interviews are cancelled until further notice. Well I got ghosted.

Interview Questions
  • Regular regression, probability and LC medium questions.
