I think it's funny how a simple question can have a answer a little difficult to being built. I always have to "overthink" about my answer and I was wondering how I could tell you how I have gotten my first job.
I'm just 18 and a few months ago, I decided to go out to job hunting, therefore, my inexperience with jobs. Unfortunately, I didn't have any good results with it.
In a conversation with a friend, I found out a job opportunity in a "power plant" (a company that work in the agribusiness area), but I should pass in a exam before the job interview.
Finally, a opportunity knock on my door and I had 9.5 out of 10 on the company's exam. Now, I'm a mechanical apprentice :D

Here's my piece of advice: If you have a opportunity, just catch it and If you lost it, head up to go on.
