1. Poor compensation
They don't offer you any other benefits expect basic ones must-required based on local labor law.
2. Heavy workload
One of my colleagues had to work until midnight. I also had to work about 12 - 13 hours per a day. It was difficult to manage workload because c-level executives consider only money.
In the end, more than half of the employees left the company in a month because they were tired of the heavy workloads.
3. Manpower shortage
Local branches have lack of manpower issues so other employees should take over multiple tasks from relevant teams.
