Interview questions [1]
Question 1

Very easy compared to the other roles at Jane Street. Got asked Probability, coding, brainteasers. Basically a mix of Quant trading and Software Engineering questions. First and Second round were much easier than final onsite round.
going through resume, explain your past experience and projects. why the company jane street and role of trading desk operations engineer intern. then logical reasoning and brain teaser type questions .
The interviewer was extremely kind, approachable, and supportive throughout the entire process, which made the overall experience much more comfortable and less stressful. The questions were largely similar to typical LeetCode-style problems, focusing on core data structures and algorithms. In addition to the coding-focused rounds, one of the initial rounds specifically tested mathematical concepts, which required a strong grasp of fundamentals and logical reasoning.
