Our candidates report that Interactive Brokers cares less about polished storytelling and more about whether you can stay accurate across a wide mix of formats. We’ve seen everything from resume walkthroughs and direct company/role questions to personality checks, logic chains, and coding problems that can jump from easy to hard without much warning. The throughline is a fairly rigid, impersonal style: interviewers tend to be straightforward, but not especially warm, and they seem to favor candidates who can answer cleanly without needing much prompting.
A recurring theme is that the technical bar is not always what people expect from the job description. One candidate expected more practical programming or systems discussion and instead saw mostly LeetCode-style coding plus logic questions, while another faced a tightly timed assessment with arithmetic, geometric math, and a practical tax-calculation problem. That tells us the company is screening for speed, precision, and comfort with applied problem-solving more than deep specialization in one area. The non-obvious trap here is mismatch: candidates who prepare for a narrow technical conversation can be caught off guard by how broad and compressed the evaluation feels.
We’ve also seen that the process can feel inconsistent in what gets emphasized, so candidates who do best are the ones who can adapt quickly when the conversation shifts. The strongest signal appears to be whether you can move fluidly between background, reasoning, and implementation without losing accuracy. In other words, Interactive Brokers seems to reward people who are steady under pressure and can handle a process that is more broadly diagnostic than deeply exploratory.

Synthesized from candidate reports. Individual experiences may vary.
The process starts with an initial recruiter call to discuss your background, the role, and basic fit. In one experience, HR also described the later rounds, though candidates noted that the actual topics sometimes differed from what was previewed.
Candidates complete a timed assessment with a mix of math questions, a personality test, and one coding problem. The math section can include arithmetic and geometric problems, and the coding task may be practical, such as calculating total taxes, or feel like a LeetCode medium.
This round is an online interview with the manager and is mostly a walkthrough of your resume and past experience. Expect direct questions about the work listed on your resume and your understanding of the company and position.
Later rounds become more technical and include coding questions that can ramp from easy to medium to hard LeetCode-style problems. One interview with the technical team also included logic questions that built on each other, along with a behavioral segment.
There is another phone interview with the hiring manager later in the process. This round continues to focus on your background, role fit, and technical depth, and may overlap with broader discussion of your experience.
The process ends with a final call involving both the hiring manager and another interviewer. This appears to be the last step before the decision, after which candidates receive either an offer or a rejection.
