Firstly you will have a first round written test and the second round written test is a programming test. The first round interview overall is hard. You will be asked anything from finance, option pricing to programming.
I applied online. I interviewed at Bloomberg (New York, NY) in Aug 2025
Interview
The interview process consisted of three 45-minute rounds across two days. The first focused heavily on Pandas with multiple questions, which felt narrowly scoped and time-pressured. The second round went better, but the final interviewer appeared late and disengaged. Communication afterward was minimal, and the role was later reposted.
Two rounds of technical (First round OA, second round coding project of PCA regression within an hour without using packages)
One round presentation to the entire team
Extremely demanding in mathematics / stochastic calculus / statistics
