Applied online at Mars.com for the role of unit specialist. Provided CV and cover letter. Following this I was invited to a telephone interview. Interview lasted around 30 minutes. Received an email confirmation 2 weeks later.

Day long normally, three parts. A team exercise, a scenario or presentation then your one to one. You can get knocked out at any stage. Often prior to this a competency test was sent out but not always. There may now br a behaviour test
