I first applied online and a couple hours after I was sent an invite to complete a situational judgement exam, upon completion of that within a couple of hours I was asked to complete a numerical test. It was not too difficult and as long as you have had practice you should fare well. Then once I passed that I was invited to a first stage interview, this interview was to take place via telephone. After a week they published available time slots, unfortunately I was not able to do any of them, as such it was three weeks from being invited to interview to actually completing the interview.
