Having instructed for almost two years i think its worth mentioning a few benefits of instructing that i think often get ignored.
Firstly instructing is usually referred to as a method of building hours but if you approach it in the correct way you also gain experience. Whilst hours and ratings are the things that will get you interviews, the intangibles that you've gained instructing, whether its simply more confidence on the radio, or perhaps a far greater understanding of instrument flying ( get your instrument restriction lifted asap!), are going to help not only in an interview situation, but during type ratings and line training.
Secondly you learn how to interact with people in a cockpit, and how to make them perform to the best of their ability. You also meet people who can give you advice and help throughout your career, its suprising how many people in the aviation industry still spend time flying at their local airfield.
Finally its great fun!
