1)Check information
Before going to an information session or undergoing a selection process, it is recommended to gather information from information on employment and job change sites, company sites, and online word-of-mouth sites.
Worth referring to when gathering information on the Internet are personal blogs or special websites ect.

2)Ask a company representative questions
What is the average number of working hours for employees who actually work?
Even under the deemed overtime pay system, if I work beyond the set hours, will I be paid overtime pay?
How long is overtime during busy periods?
What is the employee turnover rate (how long is the average length of service?)
How old are most of the people? (Are there many who quit soon?)
Please feel free to ask any questions.

3)How to distinguish from the employment contract
Black companies can be identified most accurately at the stage of concluding an employment contract.
For example, contents of job posted and employment contract are different
“I was supposed to be hired as a general employee, but I was hired as a manager”
Also, be careful if overtime pay is not specified in the first place. When signing an employment contract, be sure to check the terms carefully.
