The first step is to take an exam, which is mid-level, and after that, I took a technical interview. The interview is difficult, and it's about problem-solving; the interviewees are good

You go through an exam first - Fairly simple test that tests your IQ, English, and Problem solving skills. The technical interview follows next, where you are tested on your Problem solving skills. Lastly a management interview to review you as a person and on a more personal level.
