First stage after CV/cover letter was a 1 hour aptitude assessment (letter series, shape series, maths word problems) and 45 minute personality assessment. Nothing extremely difficult, just long. Second stage was a 20 minute Skype interview with a recruiter. This was followed by an "Ethics Assessment" which asked about things like drugs and theft in the workplace. The next stage was a proctored assessment. In my case this was literally the same 1 hour assessment I had done earlier, just done while on a Skype call with someone on the other end. The final stage I got to was a pair of hour long, one-on-one interviews done over Skype with a couple of managers. Both asked pretty much the same questions.

Terrible Interview process - highly recommend that you avoid interviewing here. The online assessment takes far too long with many questions that are completely useless and a waste of your time. For the amount of pay that they are giving and the questions asked, this should be a indicator of the quality of work going on here. Avoid.
