This is the ME.
Not surprising. For such a large company, they make some pretty strange mistakes.
Just over a year ago, I was hired by mistake! Hired in December, 2012; then contacted in April, 2013 saying I was no longer hired. Later found out that they were trying to get guys out of the pool that didn't have a Boeing or Airbus type.
The thing to expect with the likes of EK is that ANYTHING can happen. You are not fully hired until you pass your checkride.
