I had a phone interview for the Quant Finance position at Two Sigma. The interview lasted about 15 minutes and was mainly focused on technical questions related to finance and programming.
The interviewer began by asking me to introduce myself and provide an overview of my academic background and relevant experiences. After my introduction, they proceeded to ask a couple of programming questions that tested my understanding of algorithms and data structures.
One of the questions was about implementing a binary search algorithm, which I was able to solve efficiently. The interviewer then asked about my approach to optimizing the algorithm further and how I would handle edge cases.
Following the technical part of the interview, we briefly discussed my future career goals and fit within Two Sigma. The interview concluded with the interviewer giving me an overview of the next steps in the hiring process.
