Read through the negative reviews here, they are spot on. The only positive reviews in Development/IT are from the managers who are trying to increase the glassdoor rating to attract developers.
The turnover rate is so high, that you will only find two types of people in this company. The management who has been around for 20+ years, and those that recently joined the company. The only others are a handful who are trapped on a visa and have no option but to stay put.
This company runs like a start-up. No planning, waterfall model development, and complete lack of any requirements, documentation of code, area or process. The only means you have of learning about the product/code are by talking to the managers and they don't have time for you.
Managers/directors are not managers, just senior developers who have been with the company for decades and have been given the title so they don't leave. They have an entitled attitude, are occasionally very rude and you will regularly hear them use offensive language towards employees in the office.
Now, as a developer, your opinion is not valued or cared about here. There is no career progression. Management remains management and you will remain a worker cleaning up after them. Interacting and communicating with other departments is not encouraged either. You are basically to shut up and do what you are asked. Releases stretch on for months and developers/QAs are asked to work weekends for months at a time with no end in sight.
Work-life balance is very difficult. Once you join, management pretty much treats you like they own you. If you voice your opinion about changes in process or improvement, you will be looked down on, the environment will become hostile to you and you will eventually be sidelined or fired.
