I applied online. The process took 2 months. I interviewed at Mattel (Maidenhead, England) in Jul 2018
Interview
Standard competency interview and case study. Relatively long process of applying, HR responded a couple of weeks later to set up several phone interviews. This was followed with a F2F interview (submitting case study before) which was a standard CV walkthrough, competency questions & presentation F2F with line manager & HR
