Thanks so much for the tips and mentioning your experience. I believe it would be helpful for those considering doing this.
I had friends who taught English abroad before. However, I think they were just paid a small stipend for it. They mainly did it so they could find a way to travel abroad and get paid for it. So, it was mainly an exciting life experience for them before they came back home.
Good luck in applying again next year. I hope you definitely get into a position.
