I have a friend who after a lot of PPL and CPL flying finally did his ATPL parallel to some other job. Being some "old" newbie now seems to kick him out of many airline tests. Maybe it's combined with not being a 20 year old and airlines feel he is not so flexible for their company style anymore? Just meant as a word of caution for non-standard career choices. So he ends up flying business jets partly with their low proficiency owners on the left seat...
