The hiring process started with an online application with cover letter and resume.
After this there was a telephone interview consisting of the usual behavioural questions, some queries on previous work, and how my skills relate to the job/company/field.
After the telephone interview I was invited to an assessment centre which went for 1/2 a day. This consisted of a group problem solving task, then an individual problem solving task. After both tasks we had to present our solutions to others.
Finally, the final interview consisted of myself sitting with four managers of the department I would be working within. They asked about my motivations, what type of work culture I desire, and where I see myself in the company in a few years time.
