I was "let go" from the company more than a year and this was the greatest pro that ever happened to me. Currently work in a company that actually trains their new hires and treats you like a worker.
Svantaggi
As a stock market trainee, you won't be trained at all. They don't care how you get your numbers - just get it done. A speck above minimal wage starting out way below industry level even for an entry-level job. Their retention rate is very low. They hire and fire a lot at the end of the fiscal year.
