Good technology, large scale, a lot of technical problems to solve. You will learn a lot.

A lot of politics. There is no great acknowledgement of achievements. You have to deliver at every single moment in your life to reach a happy situation. Work-life balance is really bad, and it's really hard to estimate the tasks' cost.

Work here is very stressful. We are required to perform a lot of duties that other companies don't ask for. If you show some respect to this and understand how stressful employee life is, then I think you will take the right actions and provide the right employee judgment.

Also, it's not wise to estimate a very low cost for a task that should take more time than expected.
