Here's the deal, pilots are convinced their resumes and applications are only going to be read over by Chuck Yeager and Buzz Aldrin, they don't realize that it goes to HR and these companies have formalized processes these days for hiring, rather than a dart-board or picking CPT America. So while PIC will help, there are plenty of other things that do, like being a check-pilot and anything else that will get you additional aviation experience or show that you are an all-around good guy for the company. If you do nothing but fly for a regional and have nothing but your 4 year degree, then yes, you might need a lot of PIC time.
