There is four stages to the interview process. The order of these are slightly varied. At the start of the day you will either do both interviews or do the aptitude test. Once you have completed one you will move onto the other. 1a) Competency Interview - A one-on-one interview with someone in a senior role. This focuses on what you stated in your CV, while also going over experience you have gained in other jobs and in education. Expect questions such as 'where have you displayed leadership'. Lasts between 30-45 minutes. 1b) Technical Interview - A one-on-one interview. This covers a wide range of technical questions, covering details you have stated in your CV. A good knowledge of technologies you have stated in your CV will leave you in good standing. Also prepare for questions such as 'How do you deal with working under pressure / close to deadlines'. Lasts between 30-45 minutes. 2) Aptitude Test - This is completed on a computer. There are 30? questions each lasting 3 minutes to answer. There is no advantage in answering the questions quickly. Once you skip/answer a question you cannot revisit it. Questions are varied and you may not get asked the same questions as others. Questions range from working out speed given distance and time, to selecting the correct pattern when told the rules for it. This does not seem to play a critical role in the interview process, as those scoring ~40-50% make it through the process. 3) Group Interview - This will be done in a meeting room where the interviewers will sit in each corner of the room. You will be given a case study and told to come up with 3 key areas to make improvements to the company in the case study. The focus of this isn't the solutions, but how you behave and act. Once the team agrees on the 3 main areas they will improve you are asked to give a presentation to the interviewers on these ideas. How this is done in up to the team.
