As I slowly finish my application on Airlineapps.com I feel like I'm not qualified yet (perhaps nervousness)

I've been flying semi-privately for the last 10 years, mostly single engine cessna's (more than I am proud of). I've slowly reached the ATP minimums and thought of switching careers.

I've done the research and Endeavor is my top choice at the moment followed by Skywest.

Will I be frowned upon for the amount of single engine time and how long it's taken me and not opting for CFI?

Thanks
