Of course you write why you applied for Swiss .. why CCM ? what you are expecting in the future ... some stuffs like that ! Everything you have to write about even about your motivation are already written on the application form (for the motivation letter, see at the end

Swiss is currently hiring... I had my selection day on September, 6th and will begin my training on November, 20th.
I heard the next selection days are on January but I don't know when will start the next trainings...
I wish you good luck ! ! !
