The first stage is a pre-interview, which they send you via email. The pre-interview is in two parts. The first part involves calculating UIF and SDL (government benefits afforded in South Africa). The second part is a coding exercise in Ruby, which is a brain teaser. You are given a day to submit the above. If you do, you move on to the first interview where you are asked to give text book answers, without prior preparation to some common technical concepts such as: - What is password hashing? - What is a left join?
