4 stages, two face to face interviews, a puzzle questionnaire and a case study. All done in the one day in their offices. The whole process took about 3-4 hours, and there were 3 other applicants as part of the case study.

3-5 rounds depending on role and seniority. Experience, technical knowledge and some business knowledge gives you a higher chance of progressing to the next stage. The entire process takes quite a long time with some hires mentioning as long as 6 months.
