I applied through college or university. The process took 1 week. I interviewed at Citi (New York, NY) in Oct 2016
Interview
On campus interview. First he asked me about my story, and then asked me to introduce one of my internships. Later he moved on to ask me about market. Also a behavioral question "how do you resolve a conflict". 2 quant questions were asked in the end. It took 30 mins.

Question 1
Tell me about your story; Intern experiences; Insights on market; and 2 quantitative questions.
One is a probability question about poker cards, another is a programming question on how to get the nth Fibbonacci number
I applied online. I interviewed at Citi (New York, NY)
Interview
It was a first round with the hiring manager who mostly asked behavioral questions. He described the role and what they do. Overall the questions he asked were trivial like bond market trading hours. I didn’t know about the sessions after the regular trading session.

General questions about trace data and bond markets
One phone call with HR covering background. I was then invited for a technical interview online. I didn't pass the second stage so I don't know the next steps. For the technical interview I was talking with two quants.

Good overall experience. HR got in touch a few months after application. Interview was basic quant maths including probabilities, linear algebra and calculus. Interviewer was helpful when stuck with hints.
