Same as always, fill out an online application, take a test then a group interview at a Hotel in New York near LGA airport. Personally, the interview was excellent, they ask you 5 questions which you must answer with the STAR method. In the end, they did not make me the offer practically because I have visible tattoos and earrings, which I consider discrimination by Delta, because of my tattoos, which are not offensive at all. and earrings I'm not a good enough person to be an employee but I am good enough to take my money as a customer and be a passenger.
