Multiple interview stages a psychometric, video interview and then a final full assessment day. The psychometric is easy however people get caught up answering all the answers 100% instead of taking speed into account which is a big part of the exam. The video interview is also straight forward but more nerve racking than you would think, be confident, honest and don't ramble and use the 2 minutes at the end. As for the final assessment day, its long but do your research on the core values of the company, practice presenting your work and your reasoning behind it

Had an initial chat on phone with Recruiter from Version 1 for a quick run through my CV. They explained the online personality test and aptitude test process. The online tests took about an hour, you need to concentrate and be fast. The recruiter got back the next day with results and arranged interviews the next week in Version 1's offices. Technical interview and HR interview took place the same day, took about 2 hours, very friendly and positive experience.
