In 2016 - The avg new hire had around 5000TT, avg age was late 30's, and about half of every new hire class was military. The military guys brought the TT avg down. I think a solid WAG at being competitive is 7000TT civilian and 2500 Military. Hours only get you so far though. They are looking at the big picture and sometimes the small picture. Regional FO's with zero pic time were hired right along with 62 yr olds with logbooks older than that FO. I would recommend career fairs and networking to increase your odds.
