Training or explotation

Hello everyone!

I have started a new job 3 weeks ago. I thought it was a great opportunity to live on a new country and lean new things. To be honest, i love the country and its people, but the problem isn't that I'm not sure if I took a good decision accepting this job.
When the company approached me 4 months ago, everything sounded like a great opportunity. I have been offered other jobs, but I turned them down as I thought that this one would be the right one for me.
I had to wait for them for 3 months and when they finally sent me the final offer it was not what I expected. They said they'd offered me housing which is one of the unit they sell and that I could eat at the cafeteria for free too, but that the could only offer me a very low salary, as the real job would just be available in two months from now. I accept it, as I have already turned down the other offers. The apartment is really nice, but what they told me would be training it is just pure work. My boss just asked me to do things and to organize the work with the rest of them team. I had to do market research, aniline our competitor, and I have the full office schedule from 9 am to 6 pm, sometimes more.
Yesterday they paid my first salary and I was kind of frustrated. Even one day we had to travel for an event and I worked the entire day until 11 pm.
I don't know but I have a feeling they're exploiting me. What can I do? I have received zero training so far.

Your location says Tampa, so I can't tell if you are from outside the US and came to the US for a job or what. If that's the case...I would say that most American employers do not train employees, even if they say they will or call it "training." Yes, it is very irritating and stressful. But the average American employer, supervisor and/or manager believes in "throwing you into the fire" and they call that training. What that is is...you learn while you're doing the job, you make mistakes, and only then do they tell you what you were supposed to do. Or they tell you to do something, give you the bare minimum info on how to do it, then expect you to do it and maybe tell you to ask questions if you need help.

If you have a conversation with these people about this utter ridiculousness, they justify it by saying they think it's the best way to learn, i.e. you learn best/faster by just doing it...which is not true for everyone. Really, it's just them being lazy and/or, in some cases, saving money.

It sounds like exploitation. Is the salary worth staying for? Can you get out of there?
