I applied through university. The process took 3 weeks. I interviewed at Citi (Irving, TX) in Oct 2014
Interview
The process was very quick, I had one on-campus interview and then was called back for a second on site. It was very relaxed and the people were very friendly. They gave me a tour of the facility and explained their day to day operations. The interview onsite had 2 people in the room asking me questions. It was really more just holding a conversation with them.
1 interview, then openday with 3 interviews. First one quite easy, openday a bit intense with different questions and themes approached. Process lasted more than 2 months, however HR was quite helpful and responsive.
Interview questions [1]
Question 1
Motivation, different types of derivative questions etc.
It was a really good interview process that I really liked and enjoyed doing. The first round was very casual and the questions werent challenging in the slightest. It felt low pressure or stress
They asked a mix of behavioral, technical and market questions. Pretty standard interview, no huge curveballs. There were a few brain teasers and mental math questions, no paper pen allowed.
