I was there for about 3 years. Was promised a salary increase after 6 months if they liked me, I ended up with a fraction of what they had promised. I was promised 3 weeks vacation after the first year, which I never got as well because I was told they never give 3 weeks vacation to anyone. I found out almost everyone that was hired after me was given 3 weeks vacation right off the bat.
Outside of that tiny salary increase, there was basically nothing, zero performance reviews, zero advancement opportunities.
The upper management of the company seem to be completely oblivious to everything. Starting from their employees, to even how they run the company.
The only good thing about the place is the people you work with, although many people are quite miserable because of the working conditions of the place.
