Stage 1 - Written Application - personal details and had to answer 3 questions Stage 2 - An Aptitude Test - answer as many questions as possible in 30 minutes from different categories e.g. mathematical, problem-solving etc. Stage 3 - Assessment Center - Involves 3 activities - A group task (you will be given background information on an issue and then you will have to discuss as a group), a written task (you will be given another separate issue in which you have to outlay answers to questions they give you within the time limit) and an individual interview (Use the STAR technique)! Stage 4 - Interview with a group who will possibly take you on (again Use the STAR technique), examples don't necessarily have to be from that particular work area - think of extracurricular activities, volunteering, other jobs, uni etc.
*Note that questions can have two parts - and it's okay to ask the interviewer to repeat the second part if you need. Tell me a time when you've worked in a team and something hasn't worked out or Tell me a time when you've showed teamwork? What projects have you managed? Describe a time when you have not been able to meet a deadline. What happened and what did you do?
Look up and be familiar with the STAR technique when answering interview questions. Be honest with yourself! In written applications think of anything and everything that will make you stand out - Think outside the box
