They say quantitative trading is a field dominated by STEM men. Jessi decided to challenge that. She stepped into the world of finance in high heels. And she succeeded.

‍

This story is about persistence, strategy, and finding the right path. It also highlights how mentorship, careful quant interview preparation, and the right mindset help aspiring quantitative traders achieve their goals.

‍

Background & Early Challenges

I grew up on what many would call a "safe" path. I was steady and capable, but I often felt like Sisyphus—pushing one stone of achievement after another without a clear sense of purpose. It wasn’t until partway through high school overseas, when I became fascinated with philosophy, that I started asking deeper questions. I wanted each step in life to lead somewhere meaningful.

‍

Preparing for standardized tests revealed my love for logic and structure. Each choice had a measurable outcome, almost like trading. I didn’t know what Quant Trading was yet, but I was on a path suited for me—even with interests ranging from philosophy to fashion, I could thrive in a STEM-dominated field.

‍

At university, I initially focused on philosophy, but the dense reading load was exhausting. I started exploring STEM courses and, like many peers, considered investment banking. My first attempt at applications ended in rejection. Rather than feel discouraged, I realized I needed a systematic approach. Joining One Strategy Group career coaching helped me clarify my goals and turn "I can do it" into "I can do it well."

Interview Preparation & Securing the Offer

After discovering my passion for Quant Trading, I knew preparation would be key. One Strategy Group career coaching guided me through every step of preparing for top quant firm internships. They helped me understand how to approach trading interviews strategically. Each mock session, each review of probability and trading problems, built my confidence and developing my quantitative research skills.

‍

I practiced problem-solving daily. Brain teasers, probability questions, and logic challenges became part of my routine. My mentors at One Strategy Group consulting interview prep showed me how to stay calm under pressure. They emphasized clarity of thought and structured reasoning over memorization.

‍

Networking also played a critical role. My mentors taught me how to reach out strategically to alumni and industry contacts. I learned when to follow up and how to make each interaction meaningful. This was part of One Strategy Group finance recruiting guidance—turning networking into a controlled variable rather than relying on luck.

‍

Over the course of the application season, I attended over twenty final-round interviews. I faced everything from IBD and consulting to sell-side Quant roles. Each rejection felt like a lesson. Every success built my understanding of what it took to thrive in high-pressure finance roles.

‍

Finally, I received the call from IMC Trading in Chicago. They offered me the Quant Trading Summer 2026 Internship. It was the result of systematic preparation, mentorship, and persistence.

The guidance from One Strategy Group mentorship made all the difference. They understood my goals, trusted my decisions, and helped me align my preparation with the demands of top quantitative trading firms.

‍

Quant & Skills Alignment

When I started exploring finance under the guidance of my One Strategy Group mentorship, I discovered my passion for quantitative trading. It aligned perfectly with my favorite undergraduate courses: Probability and Game Theory.

I enjoyed analyzing probabilities, spotting patterns, and thinking several steps ahead. This blend of logic, intuition, and calmness under pressure suited the mindset of a Quant Trader.

‍

An interview invitation from a prop trading firm confirmed I could succeed in Quant Trading. I realized my diverse interests—from fashion to philosophy—didn’t distract me; they gave me a unique perspective for problem-solving.

Through this journey, I realized that One Strategy Group finance recruiting guidance was not just about applications. It was about understanding the kind of trader I could be. Their structured approach helped me focus on my strengths and develop skills that would stand out in high-pressure interviews.
