Pilot Preparation - Networking
It is often said that it is not what you know but who you know. This is absolutely true in the aviation industry. When the chief pilot is going through a stack of resumes to call for interviews, they have a small stack that have personal recommendations or were "walked in".
From your first flight instructor to the person that you are sitting next to at the airport, it is important to keep records and keep in touch with people who could help you later. These people will also provide valuable information on who is hiring, who to talk to, and what the company is looking for. A good idea is to keep a "black book" of friends and acquaintances. Make notes on who that person works for and how you know them.
It is also a good idea to make occasional contact with that person to let them know that you are or will be soon looking for a flying job. People like to help and you will be surprised at generosity of other pilots.
