From a personal perspective, I feel that it is a bit late to start thinking about getting a flying job after you have finished a commercial pilots licence. Well before you have even started your CPL subjects, I would have thought it prudent to get a job working somewhere in the aviation industry. Things such as Driving an ag plane loader, being a refueller, flight clerk, baggage handler, passenger loader, winchman, hangar bitch, etc etc are all things that not only give you a bit of an insight into the industry, but also give you contacts within that industry. When you come out of your CPL training, you hopefully will then have a few good aviation related references, and maybe even networked a few contacts to get yourself known. Being in the right place at the right time is definitely going to help, but you can tip the odds in your favour a bit so that it is you in the right place, not someone else. By waiting until after you have done your CPL, you are just wasting time and you are going to have to waste a lot of money keeping current so that when that job offer does come in, you can pass a check ride.
