Yes, the question inevitably asked will be " how come, after 8000 hours of purely airline flying, have you now deigned to apply for private ops"?
EMS, a personal opinion, but one formed over 15 years of private and 20 years of airline flying, so it has some foundation. It does get my hackles up when I see posts from airline pilots who feel superior by default, and how dare they not get an interview. Not here necessarily, but it is common.
