Some questions on basic probability theory, programming. We mostly talked about my career goals and I also asked them about the company, the role. All in all, the athmosphere was friendly, I recommend them.
I applied through a staffing agency. I interviewed at Citi (London, England)

Overall there are three rounds.

I applied through a recruiter. The process took 2 months. I interviewed at Citi (Budapest)
Interview
The interview process had 3 stages and altogether took approximately 10 weeks..
First an interview with the local manager and the HR. The atmosphere was very friendly, the interviewers had very professional questions about my current status and what I imagine as a workplace.
Second round was 2 technical interviews with two developers separately. They were very collegial and showed high level of professionalism. Some of the questions were very hard, going into the deepest detail of C++, others were logic exercises.
The third round was a teleconference interview with the heads of MQA. They asked about certain scenarios / challenges at my (then) current workplace and projects I have done before and how I deal with them. It was a friendly discussion with a lot of interesting topics.
