Candidatei-me por meio de uma agência de recrutamento. Fui entrevistado pela Jane Street (Londres, Inglaterra) em fev. de 2026
Entrevista
Friendly and supportive interviewer. He presented a problem and allowed me to write a solution in a language of my choice. Then he added complications and I iterated on the code. I didn't have to run any code - he said it was just to see how I think and look for clean code etc

Pergunta 1
Design a data structure and algorithms for a toy game
It was a very quick and painless process. Recruiter very responsive, kind interviewers. High implementation and difficult problems, so failed onsite after 3 interviews and a Question and Answer Session.

Did not pass the initial coding round. I tried to explain my thought in details to the interviewer but failed to translate my thought into code. So far interviewer is very nice.

Entrevista
My experience interviewing at Jane Street was definitely challenging, but also surprisingly collaborative. Instead of focusing only on whether I could get the right answer quickly, the interviewers were much more interested in how I approached problems and explained my thinking. I worked through a few coding questions involving data structures and algorithms, and there were also some probability-style questions that tested logical reasoning. The interviewers were clearly very sharp, but they were also approachable and encouraged me to talk through my thought process the entire time. When I got stuck, they would sometimes guide me with small hints so we could keep exploring the problem together. Overall, it felt less like a typical high-pressure interview and more like a thoughtful technical conversation with experienced engineers.
