Company hired some Unprofessional people with their Background checks and they terminated due to their anti company activities, and now they are the same people who spreading lies and abusing to company in GlassDoor as i have noticed.
These people are those who eat in a plate, later they do a hole in it.
They are the employees who never appreciate to their Mother company where they learnt everything.
These people are betrayed wherever they go, they spread venom.
