Slavery is part of their work culture.
- Employees are made to work on old tech so they end up loosing touch with real-world tech stack and feel useless when they apply for jobs outside.
- Makes them accept the slavery culture and has no other place to go.
- Keeps salary low and disappoints you with a sick work culture where you're not even allowed to take the leaves you've earned.
Do not join if you have self-respect and value your skills.
