Eiffle2,
In case you haven't done a search on the recent history of DESO/DEFO hiring, I'll fill you in. There isn't any. I don't know why the website is still accepting applications, but DESO/DEFO is dead as a doornail. There are a whole bunch of us who were interviewed two years ago and are still "waiting". The most recent communication from Cathay a couple of months ago was that it was unlikely any DEFO hiring until 2012. The guys I know who were there for DESO are still "waiting" as well. So, in theory it could be four years from interview to hire. In reality, I don't think they will ever hire DESO/DEFO again, but that's just my opinion.
In hindsight, it's probably a good thing they never gave me a start date. I don't know anyone there who is even remotely happy.
Don't waste your time with Cathay. If you must, put in an application, but don't expect a call for many years, if ever.
