Finding a job as a low time pilot is always tough, I recommend that a person try to take a little more initiative than the last pilot, sending a resume to a flight department is minimal effort. As mentioned in this thread, your usually not just a driver at a corporate flight department, you are actually part of a mini airline, marketing, financial planning, scheduling, maintenance etc.
Pilots that only want to be concerned with flying, shouldn't even consider going to a biz jet operation. CP's that are disappointed with experienced airline crews are probably doing a poor job of interviewing or training.
