Oxy do NOT believe anyone who tells you that you will get a quick command because of your high hours. A handful of FOs here were promised that during recruitment a few years ago and it was not true. I don't want to think the company is intentionally lying, it could be a mixup between HR and flight ops management
. Whatever the case if you join as an FO you will be at the end of a (very) long seniority line. You will get a chance at command but not out of seniority.
