I would seriously recommend a long hard think before going down this route.
For a start NJE have stopped hiring from outside Portugal. Labour is cheap there and in their shortsightedness the company would rather hire unskilled labour, drop them in a seat in the office and forget to train them. It is all too common to simply fire people for screwing up when in reality they have been given little help. There are one or two managers and supervisors there who have floated to the the top, are hopelessly out of their depth and blame their failings on their subordinates.
Another tactic is for the company to keep staff on probation for a long, long time which then helps in the firing process (it is very difficult to fire a full time employee in Portugal). God knows they need experienced ops people who are good at their job but they simply won't hire them.
Try reading some of the threads in the bizjet forum. The way the company treats their pilots is a good indication of what you could expect.
