DL is waiting on approval to hire, but with over 2/3's of the office nearing or over retirement age in the next 5 years there will be lots of opportunity. Latest rumors I've heard are a class in the September/October time frame. Do not know how many they look to hire but it should be significant. Last year they hired 25. If it's one class, I'd guess somewhere between 10-14 but it's anyone's guess.
If you want in at DL then yes, 3 dispatch / operations management years is mandatory. Or is it 10 years? :stir:
Then you go though the resume review. (Only 2 of the last 25 were only line dispatchers. The experience ranged from dispatch supervisors though OCC Managers)
Then you get the infamous testing battery. (Where 2/3's of the applicants fail)
The lucky 1/3 gets an interview.
Good Luck.
