Candidate interview experiences
First-hand accounts from people who interviewed at Trexquant Investment.
Quantitative Researcher
First, there was an HR call where they asked some basic behavioral questions about my previous work. Then, a technical interview followed, covering my resume and a Leetcode medium question. The final stage is an onsite superday, which I haven't attended yet.
- Can you tell me about your previous experiences?
- Have you practiced Leetcode medium problems?
- Could you go over your resume with me?
Quantitative Researcher
They asked me if I knew what the company does. I said alpha factor research and then they gave me a corporate monologue with buzzwords like "innovative" and "cutting-edge" which didn't clarify anything. Basic distinctions between investment banking divisions seemed new to them, and a question about visa sponsorship turned into an immigration law seminar. After half an hour of circular talk and confusion, it seemed curiosity and competence were not required.
- Do you need visa sponsorship? What exactly is E2 dependent?
Quantitative Researcher
First, there was a take-home assignment: the hangman problem, which I had a week to complete. Then, an HR interview covering basic HR questions and one Leetcode-style coding problem. This was followed by a technical interview with the team lead for the team I would be joining. Finally, I had an interview with the CEO, which was a mix of technical and behavioral questions.
- Solve the hangman problem in one week.
- Basic HR questions + 1 Leetcode style coding problem.
- Technical Interview by the person leading the team you're assigned to.
