Networking is vital in this industry. It starts when you begin flying. eg You hopefully make a good impression at the flying school. Your instructor gets a charter/airline job and remembers you. You mix with people at the flying school's social nights. You meet people at the PPRuNe bashes... The list goes on. The trick is not to make a fool of yourself or be a pain. Stay in contact!. .At the end of the day, the airline/charter organisation is looking for someone with not only the technical ability to do the job but some one with the personal skills to get on with a variety of people. They will get an idea about that from a personal recommendation. In a few companies, the final decision is down to "Can I sit next to this person for 8 hours? Could I do an overnight with this person?"
