Interactive Brokers Software Engineer candidates describe an interview path that can combine a recruiter conversation, a timed assessment, manager-led resume discussion, and later technical and behavioral conversations. Prepare for both speed and explanation. One candidate who completed a longer process reported an assessment with math questions, a personality test, and a coding problem resembling a medium LeetCode question. A separate senior-engineering report described a one-hour assessment containing five arithmetic or geometry questions plus a tax-calculation coding task.
The manager discussion in the longer report focused heavily on walking through the candidate’s resume and listed experience. Be ready to explain your contributions, choices, and familiarity with the company and role in direct terms. That candidate also encountered later coding questions ranging from easy to hard, plus linked logic questions in a technical team interview; a behavioral segment occurred with the same interviewer. They noted that the topics described in advance did not always match the questions asked, so flexible preparation matters more than assuming a fixed agenda.
The evidence is limited to two candidate accounts, and the reported paths differ by seniority and stage reached. Practice concise math reasoning, timed implementation, and a clear resume narrative alongside coding fundamentals.

The process was longer than I expected and ended up taking about two months. It started with a recruiter phone screen, then an online assessment that had a couple of math questions, a personality test, and one coding problem that felt like a LeetCode medium. After that I moved into an online interview with the manager, which was mostly about walking through my resume and describing the experience I had listed there. The later rounds were more technical than the early ones, and the questions ramped up from easy to medium to hard LeetCode-style problems. I also had a technical teams interview where they asked logic questions that built on each other, plus a behavioral segment with the same interviewer that felt pretty impersonal. There was another phone interview with the hiring manager, and then a final call with both of them.
What stood out most was that HR didn't always describe the rounds accurately. I was told certain topics would come up at specific stages, but when I showed up, different things were actually covered. I also expected more practical programming or system-related discussion, but there was no Linux or anything like that, even though the role seemed junior enough that programming felt like it would be a nice-to-have rather than the whole focus. The interviewers were mostly basic and direct about my background and what I knew about the company and position, but the process felt a bit rigid and impersonal overall. I ended up getting the offer. My main takeaway is to be ready for a fairly broad mix: resume walkthroughs, personality and logic tests, and coding questions that can go from easy to hard without much warning.
Prep tip from this candidate
Be ready for an online assessment that combines a couple of math questions, a personality test, and at least one LeetCode-medium coding problem. Also practice explaining your resume clearly, since the manager round focused heavily on background and the experience you listed.

Synthesized from candidate reports. Individual experiences may vary.
One Software Engineer candidate reported starting with a recruiter phone screen. The account does not specify questions, so candidates may use this stage to prepare a concise overview of their background and interest in the role.
Candidates report assessment formats that pair math with coding. One account included math questions, a personality test, and a medium-difficulty LeetCode-style problem; another described five arithmetic or geometry questions and a tax-calculation task in one hour.
In one report, an online manager interview was mostly a walkthrough of the candidate’s resume and prior experience. Prepare to explain what you worked on, the decisions you made, and the skills represented on your resume.
One candidate reported later coding questions that increased from easy to hard, plus a technical team interview with logic questions that built on each other. The same interviewer also conducted a behavioral segment.
The longer account included another phone interview with the hiring manager followed by a final call involving the manager and another interviewer. Candidates should expect late-stage conversations to revisit fit and technical readiness, though the exact topics were not reported.
