Outdated technologies, and it's hard to integrate new technologies to the existing products since they're very old and complicated and there's a lot of legacy code. You should take that into account that you'd be considerably behind the times once you return to the market.
Very hard to get a raise.
No bonuses.
As a woman, men got higher pay doing the same job.
As an associate, I had the same pay as a colleague of mine who worked there for10 years.
You only get stock after a few years of work.
Not a lot of quality company events or bonus perks.
