Salaries are very low, and even if you ask to review your salary and they reviewed, be ready that ur salary will be increased 50-100$ Gross.
If you are promoted, be also ready that they will not raise your salary, only your title.
Management thinks that working as middle or senior level but having junior salary is okay and you need be satisfied with it.
Plus, be ready that you might be fired without any notice period to find other job.
