Is it a lie for Nanchang Xinda Human Resources Co., Ltd. to find a summer job?

This company recruited more than 100 people in our school last year. It happened that my classmate went there. Later, she came back and said that the work was very tiring, but the salary was ok. Before going, she also checked her papers. They are all legal enterprises. However, people who want to take part in summer jobs should be cautious. There are too many liars now, just find a reliable one.
