When are they going to close the aplication window?
As soon as they meet the requirements.
Why aren't they using CTC for the recruitment?
It's a self-run recruitment. Unlike easyJet UK, the swiss are not committed to hire through ctc or Parc => better if you know someone in the management team...
How many people do they need?
Not sure. A new aircraft is arriving soon, and quite a few FO's are leaving to BA. I'd say around 15.
Are they planning to grow?
Geneva is approaching its maximum capacity in terms of a/c based there, but BSL is still growing. And Zurich is still an option that is being considered.
good luck.
