Pros
Good autonomy and possibility to influence if you perform well
Cons
They might trust you, but you cannot trust them. They gave my word to hire me as a part time freelance after my work as employee (I needed time for personal projects), but at the last minute, after I registered my company and declined a job offer, they changed their mind. I had to find another job in emergency to avoid economical difficulties, as I would not get unemployment benefits. I lost lots of economy to live without income, during the one month that took finding a new job.
During the 4 months of my employment, I saw 7 persons over the 12 hired by the company, being fired or going away.
