Is it a liar for boos to directly recruit telemarketing posts?

The sales customer service directly hired by boss is credible. Sales customer service is actually telemarketing. The daily work is to call customers, recommend products to customers, and try our best to persuade customers to buy products. Now many enterprises will have customer service sales departments, such as telecommunications, mobile, China Unicom, banks, etc., which need a lot of telephone customer service. The recruitment is real.
