It was a swift process. After the initial screening call with the recruiter, we proceeded to a take home test which was followed by an on-site interview (these were pre-pandemic times). The one-site technical interview was split into two parts, separated by lunch. First, you were given a test of 5 or so many small-to-medium problems and you could prepare your answers in a separate room, alone. You were given a PC (without internet connection) and ample time (3+ hours) to work through them. This was followed by the actual interview with two senior members of the team. They went through your solutions and asked questions on how you would alter them if certain conditions of the exercise were no longer met or changed. A very friendly and fun experience even though you had to be careful and very precise to satisfy the interviewers' curiosity and expected skill level.
