Interactive Brokers Junior Software Developer interview questions

The process took 4 weeks!! So much delay and anxiety. Such a horrible experience. You call us for four rounds and then put us <> for HR. Worst and most mentally draining process of all. No communication for a straight week. Even if I got selected, I'd find it hard to say anything good about the interview process.

There was an online test first, then three personal rounds. In each round the applicant is tested in his/her mathematical, problem-solving and programming skills. Usually in English or at least a part of it is English.
