You get your CJO at interview, then once HR ducks are in a row, you'll get an email with a class date. You can ask for one class delay. But as others stated, take the first class. Between F9 and NK hiring, every month you wait could be 100+ seniority spots. NK is aiming to hire over 900 this year-per today's town hall and F9 goal is 40+ a month.
