First-hand accounts from people who interviewed at Radix Trading.
Quantitative Researcher
Had a super day with about 5-6 interviewers who had diverse backgrounds, including the two cofounders. It was a long day. The people were smart. The office location is good. It's still a small company, but it's growing fast and is very technically driven.
- Could you write Python code to generate all permutations of a list of integers from 1 to n, and then analyze the time and memory complexity of your algorithm, aiming for optimal solutions?
Quantitative Researcher
I had an initial one-on-one interview near my school. It included two technical questions and a chat about my interest in the company. Later, I had an on-site interview day a few months after. Several candidates and Radix employees, including the founders, were present. We candidates rotated through interviews with the employees, each lasting an hour. In total, I saw 5 interviewers. There was also a one-hour break for a free lunch. Each interview was quite relaxed, with maybe one or two technical questions from the interviewer, and discussions about their work at Radix and the company culture.
- What's the largest set of boxes from a given collection that can be nested sequentially?
- Given a linked list representing stock bids and asks, how would you clear the trades?
Quantitative Researcher
The first interview was virtual and covered probability and algorithm questions, requiring C++. It was part of a 'Superday' which included 3 more rounds focused on probability and algorithms. There was also a 1-hour presentation of my PhD research. I haven't heard back in 3 weeks after the superday and I've followed up multiple times, but got ghosted.
- Questions on probability and algorithms, to be answered using C++.
