MK is really 'set up' for folk who live in Africa. Your $5000 goes a lot further there. If you live and pay taxes in Europe its NOT a good salary.
Nearly 3 years since I did selection at MK. Sim ride standard stuff. Tech questionnaire - some of it poorly worded so that occasionally it could be 2 correct answers. Interview with 2 guys - a bit about you and your experience and a lot about why you want to be in MK. Your face will have to fit - they are a tight knit bunch who work hard in some difficult places all over the world.
Might be worth asking this on the African forum - you will likely get more responses.
