I applied through an employee referral. I interviewed at Citi (New York, NY)
Interview
6 candidates, all with very competitive background. There were coding, math tests and case study. The coding and math were easy, but I screwed up in case sudy. The case study is more like consulting.
Interview questions [1]
Question 1
coding: the hardest one is related to binary tree
math: probability and statistics
case study: I can't be specific and I don't think they will make it the same every year
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.

Easy questions about analysis, stochastic analysis and easy probability such as expected length of the smallest piece of a randomly broken stick.

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.
