I applied online. I interviewed at Interactive Brokers in Feb 2026
Interview
7 stage interview process, took 2 months. personality test, logic test, then 5 interviews. Ghosted after final interview follow-ups. Very frustrating considering the pay band for the position and the work hours requires regular weekend work along with fully in-office starting at 7am. HR would say interview would cover certain topics at stages, but on showing up, other items were actually covered.
Interview questions [1]
Question 1
phone screen, leetcode easy, leetcode medium, leetcode hard, then hiring manager (behavioural). no linux...thought programming would be a nice-to-have for what seemed like junior position. Prepped for other companies so got lucky I thought.
First, it comes with a short interview with HR. Written test followed by an interview. Simple maths and logic questions for the written test. Not many technical questions during the interview. Followed by a final interview with the head of area.

Question 1
They ask for the self introduction and continued the chatting with that.
Quick and straightforward interview process overall. The team was well-organized and moved quickly through each stage, which made the experience efficient and stress-free. Communication was timely and consistent—they kept me updated throughout and always responded promptly to any questions. I appreciated that they were transparent about expectations, timelines, and the role itself. There was no guesswork or uncertainty at any point, and I never felt ignored or “ghosted.” Overall, a very professional and honest interview experience.
