As an intern, a communication company came to recruit me. They all work as regional communication maintenance agents. Which company should I choose?

I have heard about the second company. It is equivalent to a leather company that does communications maintenance. If the employee wins the bid, he will be hired immediately. When the contract expires, the company will leave. This is great. You don’t have to maintain employees, which saves costs. It just takes a few people to hold up the scene, and don’t let Party A find fault. The treatment can be imagined. Besides, the industry itself has low profits from communication maintenance. There is no personal improvement
