Applied through the GradX program. Sent through my CV and cover letter and then progressed through the aptitude tests. Progressed through these and then went in person for an interview.
Interview process was rigorous but fair.
The GradX application process is very thorough. It starts with a questionnaire and an aptitude test, and if you perform well and have a strong resume you get shortlisted into a group of ~30 others. The company then flies everyone to a major city such as Sydney, and conducts interviews and group tasks etc. to further assess the applicants, and introduce them to the company. A few weeks later you will be notified if your application was successful. It's stressful but it allows the company to only take on high performing individuals.
