I went to an interview in mid January. I e-mailed Eurocontrol last friday and they told me that the last interviews were scheduled to take place in the end of February.
A colleague of mine is heading for Maastricht for an interview on February 25th so I guess the chances are still there.
I heard rumours that they've already hired controllers to start in mid March but since they are still interviewing people I guess they haven't decided who they want for the training in July.
