You are expect to work day and night, operators/ supervisors might call you anytime to get things done as the factory is run 24 hours a day.
The management is like typical "Chinaman" Company, save cost and encourage working for long hours.
Depending on your manager/ superior, some provide good guidance, but some instruct you to do somethings misaligned with company direction.
Company only recruit fresh grad as most with working experience wont like the culture there. Everyday need to write daily working report and weekly report. You spent hours doing the writing but nobody cares. If you didnt submit, then there will be penalty.
