Very Bad Experience - Business Reporting Analyst Acara Solutions Employee Review

I had a very bad experience working for this company. I got hired as a Business Analyst. My job was to prepare analytics on Microsoft Excel. I did not get any proper training. In spite of that, I did my best to get upto speed. In addition, my coworkers were extremely demanding. After a few months, they just suddenly called me, and without giving any proper reason, they terminated my employment, inspite of the fact that I was getting better. They did it in such an unprofessional manner and it was the most humiliating experience of my life.
