-First round phone/zoom interview, some math/probability problems and I spent a while talking about my academic research -"Superday" on site interview, several other candidates there too. Met with several people and gave a research talk. Everyone was very friendly.
Interview questions [1]
Question 1
-Give a 45-minute academic-style talk on your research -Describe an efficient algorithms for some problems -Derive the formula for least squares regression and its assumptions -Find a Nash equilibrium for a game involving probability -Write pseudocode for a dynamic programing algorithm for a trading-based problem
Super day with 5-6 interviewers from diverse background including two cofounders. A long day. People are smart. Office location is good. Still small company though but growing fast. Very technical driven.

Question 1
Write python code to output all permutations of the list of integers from one to n. Analyze the time and memory complexity of the algorithm. Try to find the optimal solutions.
I applied online. The process took 2 months. I interviewed at Radix Trading (Chicago, IL) in Oct 2024
Interview
- First round virtual interview on probability and algorithm questions, must use C++
- Superday. 3 interview rounds still on probability and algorithms. A 1-hour talk on my PhD research
Last communication was 3 weeks after the superday. Got ghosted afterwards despite multiple follow-ups.
