First-hand accounts from people who interviewed at Old Mission.
Quantitative Trader
Took a Hackerrank test with 35 probability questions and 1 coding question. The probability questions were medium difficulty and the coding question was also medium. The questions got progressively harder, ranging from brainteasers to numerical computation. The Python question at the end was standard.
- What is the probability of rolling an 8 with two 6-sided dice?
Research Analyst
People there are super nice and the culture looks amazing. They ask Fermi estimate questions and why you're interested in the company and the role. I really enjoyed the culture there, and it seemed less intense than other MM firms. You should have deep knowledge on how the stock price moves.
- What are your reasons for wanting this particular role?
- What makes you want to work for this company?
Quant Researcher
Had an initial soft chat with HR. Then, I interviewed with someone they called the 'head of education'. All the questions were about the implementation details of algorithms I use. After that, I was rejected without even a hard technical interview. I tried to get feedback from the recruiter but never heard back. My impression is that this company might be interviewing to gather information about competitors. I'd recommend avoiding them.
- Could you elaborate on the specifics of certain algorithms?
- Can you provide details on the implementation of specific algorithms?
Software Engineer
The interview started with an online assessment that had multiple-choice questions and a couple of easy to medium coding problems in any programming language. A few days later, I had an informational call with Old Mission, which was quite long and unstructured. At the end of the call, I scheduled a coding interview. The first coding problem was of medium difficulty, followed by a question about a data structure. After doing well, I scheduled another phone call but they never called me back, which was a bad look for the company. The second technical interview was rough, with lots of questions on Linux, hardware, and low-level programming/concurrency. I got rejected a week after that.
- Can you explain the computer power-on sequence?
- What are some 2-letter bash commands you know?
- Describe what occurs when data is printed to STDOUT.
