I applied online. The process took 2 weeks. I interviewed at Citi (New York, NY) in Dec 2019
Interview
Applied online, had a phone screen with someone from the quant department. Some behavioral questions, some probability riddles, and some basic computer programming questions. Invited for a superday to their NY headquarters which included a math test, a computer programming test, and a few rounds of interviews.

Question 1
Mostly standard behavioral questions (i.e. tell me about a time you faced an ethical dilemma in class or at work). Included a case study about investment recommendations, so make sure you know some factors that have been affecting markets recently.

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.

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.

Interview
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.
