Q&A with Optiver Intern

How did you apply for this internship at Optiver?

I saw the internship posting on OpenQuant and applied there. In general, I also keep a list of quant firms I'm interested in and occasionally scan their career pages for open opportunities.

What do you think allowed you to pass the resume screen?

I already had a quantitative trading internship at a mid-tier firm under my belt from last summer. I also attend a university that is a "quant feeder".

What was the structure of the interview process?

  • Round 1: Online Assessment
  • Round 2: Recruiter Phone Call
  • Round 3: Technical Phone Screen
  • Round 4: Final Round (Combination of Technical and Behavioral)

The online assessment was the classic 80 in 8 mental math game, followed by a reflex game, finding the missing value in the sequence, and probability puzzles. I also had a few standard behavioral questions about my interest and alignment with Optiver. The technical questions that appeared in the later rounds were quite similar those that were in the green book.

How did you prepare for the interview rounds?

For the mental math and sequences portions of the interview, I used Tradermath and OpenQuant Mental Math to practice. I also read through the Green Book and Heard on the Street for practice problems.

What advice would you give students looking to land an internship at Optiver?

My biggest piece of advice would be to focus on the fundamentals. Many, including myself, often get caught up in grinding out problems without having solid foundations in probability and statistics. The reality is that you'll likely be presented with a question you've never seen before during your interviews. Having solid foundations will equip you with the repertoire of skills to solve these questions with ease.

What are some misconceptions you had about interviewing at Optiver?

Going into my interviews, I was under the impression that I would have to know a lot of in-depth financial knowledge to land the offer. From my experience, I found that Optiver placed more emphasis on problem-solving ability and quantitative skills than finance knowledge.
