Career path is not well defined, not all employees know exactly what is required from them to progress, and it is left to the leaders/managers to decide the promotions.

They pay above-average salaries for the juniors and good salaries for the seniors without any additional benefits except the health insurance, which covers the employees, not their families. Also, we don't have any other benefits outside the company, such as offers for transportation, tourism, restaurants, or even gyms! This is why some employees leave the company, as they would be paid or save more, in general.
